The Message class provides a single point of access to all things to do with an email message.
You create a new email message by calling the ::new method, or just Mail.new
A Message object by default has the following objects inside it:
A Header object which contians all information and settings of the header of the email
Body object which contains all parts of the email that are not part of the header, this includes any attachments, body text, MIME parts etc.
2.1. General Description At the most basic level, a message is a series of characters. A message that is conformant with this standard is comprised of characters with values in the range 1 through 127 and interpreted as US-ASCII characters [ASCII]. For brevity, this document sometimes refers to this range of characters as simply "US-ASCII characters". Note: This standard specifies that messages are made up of characters in the US-ASCII range of 1 through 127. There are other documents, specifically the MIME document series [RFC2045, RFC2046, RFC2047, RFC2048, RFC2049], that extend this standard to allow for values outside of that range. Discussion of those mechanisms is not within the scope of this standard. Messages are divided into lines of characters. A line is a series of characters that is delimited with the two characters carriage-return and line-feed; that is, the carriage return (CR) character (ASCII value 13) followed immediately by the line feed (LF) character (ASCII value 10). (The carriage-return/line-feed pair is usually written in this document as "CRLF".) A message consists of header fields (collectively called "the header of the message") followed, optionally, by a body. The header is a sequence of lines of characters with special syntax as defined in this standard. The body is simply a sequence of characters that follows the header and is separated from the header by an empty line (i.e., a line with nothing preceding the CRLF).
If you assign a delivery handler, mail will call :deliver_mail on the object you assign to #delivery_handler, it will pass itself as the single argument.
If you define a #delivery_handler, then you are responsible for the following actions in the delivery cycle:
Appending the mail object to Mail.deliveries as you see fit.
Checking the mail.perform_deliveries flag to decide if you should actually call :deliver! the mail object or not.
Checking the mail.raise_delivery_errors flag to decide if you should raise delivery errors if they occur.
Actually calling :deliver! (with the bang) on the mail object to get it to deliver itself.
A simplest implementation of a #delivery_handler would be
class MyObject def initialize @mail = Mail.new('To: mikel@test.lindsaar.net') @mail.delivery_handler = self end attr_accessor :mail def deliver_mail(mail) yield end end
Then doing:
obj = MyObject.new obj.mail.deliver
Would cause Mail to call obj.deliver_mail passing itself as a parameter, which then can just yield and let Mail do it’s own private do_delivery method.
If set to false, mail will go through the motions of doing a delivery, but not actually call the delivery method or append the mail object to the Mail.deliveries collection. Useful for testing.
Mail.deliveries.size #=> 0 mail.delivery_method :smtp mail.perform_deliveries = false mail.deliver # Mail::SMTP not called here Mail.deliveries.size #=> 0
If you want to test and query the Mail.deliveries collection to see what mail you sent, you should set #perform_deliveries to true and use the :test mail #delivery_method:
Mail.deliveries.size #=> 0 mail.delivery_method :test mail.perform_deliveries = true mail.deliver Mail.deliveries.size #=> 1
This setting is ignored by mail (though still available as a flag) if you define a #delivery_handler
If set to false, mail will silently catch and ignore any exceptions raised through attempting to deliver an email.
This setting is ignored by mail (though still available as a flag) if you define a #delivery_handler
Provides the operator needed for sort et al.
Compares this mail object with another mail object, this is done by date, so an email that is older than another will appear first.
Example:
mail1 = Mail.new do date(Time.now) end mail2 = Mail.new do date(Time.now - 86400) # 1 day older end [mail2, mail1].sort #=> [mail2, mail1]
# File lib/mail/message.rb, line 309 def <=>(other) if other.nil? 1 else self.date <=> other.date end end
Two emails are the same if they have the same fields and body contents. One gotcha here is that Mail will insert Message-IDs when calling encoded, so doing mail1.encoded == mail2.encoded is most probably not going to return what you think as the assigned Message-IDs by Mail (if not already defined as the same) will ensure that the two objects are unique, and this comparison will ALWAYS return false.
So the == operator has been defined like so: Two messages are the same if they have the same content, ignoring the Message-ID field, unless BOTH emails have a defined and different Message-ID value, then they are false.
So, in practice the == operator works like this:
m1 = Mail.new("Subject: Hello\r\n\r\nHello") m2 = Mail.new("Subject: Hello\r\n\r\nHello") m1 == m2 #=> true m1 = Mail.new("Subject: Hello\r\n\r\nHello") m2 = Mail.new("Message-ID: <1234@test>\r\nSubject: Hello\r\n\r\nHello") m1 == m2 #=> true m1 = Mail.new("Message-ID: <1234@test>\r\nSubject: Hello\r\n\r\nHello") m2 = Mail.new("Subject: Hello\r\n\r\nHello") m1 == m2 #=> true m1 = Mail.new("Message-ID: <1234@test>\r\nSubject: Hello\r\n\r\nHello") m2 = Mail.new("Message-ID: <1234@test>\r\nSubject: Hello\r\n\r\nHello") m1 == m2 #=> true m1 = Mail.new("Message-ID: <1234@test>\r\nSubject: Hello\r\n\r\nHello") m2 = Mail.new("Message-ID: <DIFFERENT@test>\r\nSubject: Hello\r\n\r\nHello") m1 == m2 #=> false
# File lib/mail/message.rb, line 348 def ==(other) return false unless other.respond_to?(:encoded) if self.message_id && other.message_id result = (self.encoded == other.encoded) else self_message_id, other_message_id = self.message_id, other.message_id self.message_id, other.message_id = '<temp@test>', '<temp@test>' result = self.encoded == other.encoded self.message_id = "<#{self_message_id}>" if self_message_id other.message_id = "<#{other_message_id}>" if other_message_id result end end
Allows you to read an arbitrary header
Example:
mail['foo'] = '1234' mail['foo'].to_s #=> '1234'
# File lib/mail/message.rb, line 1233 def [](name) header[underscoreize(name)] end
Allows you to add an arbitrary header
Example:
mail['foo'] = '1234' mail['foo'].to_s #=> '1234'
# File lib/mail/message.rb, line 1215 def []=(name, value) if name.to_s == 'body' self.body = value elsif name.to_s =~ %rcontent[-_]type/ header[name] = value elsif name.to_s == 'charset' self.charset = value else header[name] = value end end
# File lib/mail/message.rb, line 1482 def action delivery_status_part and delivery_status_part.action end
Adds a content type and charset if the body is US-ASCII
Otherwise raises a warning
# File lib/mail/message.rb, line 1376 def add_charset if !body.empty? # Only give a warning if this isn't an attachment, has non US-ASCII and the user # has not specified an encoding explicitly. if @defaulted_charset && body.raw_source.not_ascii_only? && !self.attachment? warning = "Non US-ASCII detected and no charset defined.\nDefaulting to UTF-8, set your own if this is incorrect.\n" STDERR.puts(warning) end header[:content_type].parameters['charset'] = @charset end end
Adds a content transfer encoding
Otherwise raises a warning
# File lib/mail/message.rb, line 1391 def add_content_transfer_encoding if body.only_us_ascii? header[:content_transfer_encoding] = '7bit' else warning = "Non US-ASCII detected and no content-transfer-encoding defined.\nDefaulting to 8bit, set your own if this is incorrect.\n" STDERR.puts(warning) header[:content_transfer_encoding] = '8bit' end end
Adds a content type and charset if the body is US-ASCII
Otherwise raises a warning
# File lib/mail/message.rb, line 1369 def add_content_type header[:content_type] = 'text/plain' end
Creates a new empty Date field and inserts it in the correct order into the Header. The DateField object will automatically generate DateTime.now’s date if you try and encode it or output it #to_s without specifying a date yourself.
It will preserve any date you specify if you do.
# File lib/mail/message.rb, line 1352 def add_date(date_val = '') header['date'] = date_val end
Adds a file to the message. You have two options with this method, you can just pass in the absolute path to the file you want and Mail will read the file, get the filename from the path you pass in and guess the MIME media type, or you can pass in the filename as a string, and pass in the file content as a blob.
Example:
m = Mail.new m.add_file('/path/to/filename.png') m = Mail.new m.add_file(:filename => 'filename.png', :content => File.read('/path/to/file.jpg'))
Note also that if you add a file to an existing message, Mail will convert that message to a MIME multipart email, moving whatever plain text body you had into it’s own text plain part.
Example:
m = Mail.new do body 'this is some text' end m.multipart? #=> false m.add_file('/path/to/filename.png') m.multipart? #=> true m.parts.first.content_type.content_type #=> 'text/plain' m.parts.last.content_type.content_type #=> 'image/png'
See also attachments
# File lib/mail/message.rb, line 1663 def add_file(values) convert_to_multipart unless self.multipart? || self.body.decoded.blank? add_multipart_mixed_header if values.is_a?(String) basename = File.basename(values) filedata = File.open(values, 'rb') { |f| f.read } else basename = values[:filename] filedata = values[:content] || File.open(values[:filename], 'rb') { |f| f.read } end self.attachments[basename] = filedata end
Creates a new empty Message-ID field and inserts it in the correct order into the Header. The MessageIdField object will automatically generate a unique message ID if you try and encode it or output it #to_s without specifying a message id.
It will preserve the message ID you specify if you do.
# File lib/mail/message.rb, line 1342 def add_message_id(msg_id_val = '') header['message-id'] = msg_id_val end
Creates a new empty Mime Version field and inserts it in the correct order into the Header. The MimeVersion object will automatically generate set itself to ‘1.0’ if you try and encode it or output it #to_s without specifying a version yourself.
It will preserve any date you specify if you do.
# File lib/mail/message.rb, line 1362 def add_mime_version(ver_val = '') header['mime-version'] = ver_val end
Adds a part to the parts list or creates the part list
# File lib/mail/message.rb, line 1607 def add_part(part) if !body.multipart? && !self.body.decoded.blank? @text_part = Mail::Part.new('Content-Type: text/plain;') @text_part.body = body.decoded self.body << @text_part add_multipart_alternate_header end add_boundary self.body << part end
# File lib/mail/message.rb, line 1779 def all_parts parts.map { |p| [p, p.all_parts] }.flatten end
Returns the attachment data if there is any
# File lib/mail/message.rb, line 1770 def attachment @attachment end
Returns true if this part is an attachment, false otherwise.
# File lib/mail/message.rb, line 1765 def attachment? !!find_attachment end
Returns an AttachmentsList object, which holds all of the attachments in the receiver object (either the entier email or a part within) and all of it’s descendants.
It also allows you to add attachments to the mail object directly, like so:
mail.attachments['filename.jpg'] = File.read('/path/to/filename.jpg')
If you do this, then Mail will take the file name and work out the MIME media type set the Content-Type, Content-Disposition, Content-Transfer-Encoding and base64 encode the contents of the attachment all for you.
You can also specify overrides if you want by passing a hash instead of a string:
mail.attachments['filename.jpg'] = {:mime_type => 'application/x-gzip', :content => File.read('/path/to/filename.jpg')}
If you want to use a different encoding than Base64, you can pass an encoding in, but then it is up to you to pass in the content pre-encoded, and don’t expect Mail to know how to decode this data:
file_content = SpecialEncode(File.read('/path/to/filename.jpg')) mail.attachments['filename.jpg'] = {:mime_type => 'application/x-gzip', :encoding => 'SpecialEncoding', :content => file_content }
You can also search for specific attachments:
# By Filename mail.attachments['filename.jpg'] #=> Mail::Part object or nil # or by index mail.attachments[0] #=> Mail::Part (first attachment)
# File lib/mail/message.rb, line 1550 def attachments parts.attachments end
Returns the Bcc value of the mail object as an array of strings of address specs.
Example:
mail.bcc = 'Mikel <mikel@test.lindsaar.net>' mail.bcc #=> ['mikel@test.lindsaar.net'] mail.bcc = 'Mikel <mikel@test.lindsaar.net>, ada@test.lindsaar.net' mail.bcc #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
Also allows you to set the value by passing a value as a parameter
Example:
mail.bcc 'Mikel <mikel@test.lindsaar.net>' mail.bcc #=> ['mikel@test.lindsaar.net']
Additionally, you can append new addresses to the returned Array like object.
Example:
mail.bcc 'Mikel <mikel@test.lindsaar.net>' mail.bcc << 'ada@test.lindsaar.net' mail.bcc #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
# File lib/mail/message.rb, line 474 def bcc( val = nil ) default :bcc, val end
Sets the Bcc value of the mail object, pass in a string of the field
Example:
mail.bcc = 'Mikel <mikel@test.lindsaar.net>' mail.bcc #=> ['mikel@test.lindsaar.net'] mail.bcc = 'Mikel <mikel@test.lindsaar.net>, ada@test.lindsaar.net' mail.bcc #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
# File lib/mail/message.rb, line 486 def bcc=( val ) header[:bcc] = val end
Returns an array of addresses (the encoded value) in the Bcc field, if no Bcc field, returns an empty array
# File lib/mail/message.rb, line 1205 def bcc_addrs bcc ? [bcc].flatten : [] end
Returns the body of the message object. Or, if passed a parameter sets the value.
Example:
mail = Mail::Message.new('To: mikel\r\n\r\nThis is the body') mail.body #=> #<Mail::Body:0x13919c @raw_source="This is the bo... mail.body 'This is another body' mail.body #=> #<Mail::Body:0x13919c @raw_source="This is anothe...
# File lib/mail/message.rb, line 1149 def body(value = nil) if value self.body = value # add_encoding_to_body else process_body_raw if @body_raw @body end end
Sets the body object of the message object.
Example:
mail.body = 'This is the body' mail.body #=> #<Mail::Body:0x13919c @raw_source="This is the bo...
You can also reset the body of an Message object by setting body to nil
Example:
mail.body = 'this is the body' mail.body.encoded #=> 'this is the body' mail.body = nil mail.body.encoded #=> ''
If you try and set the body of an email that is a multipart email, then instead of deleting all the parts of your email, mail will add a text/plain part to your email:
mail.add_file 'somefilename.png' mail.parts.length #=> 1 mail.body = "This is a body" mail.parts.length #=> 2 mail.parts.last.content_type.content_type #=> 'This is a body'
# File lib/mail/message.rb, line 1135 def body=(value) body_lazy(value, 0) end
# File lib/mail/message.rb, line 1159 def body_encoding(value) if value.nil? body.encoding else body.encoding = value end end
# File lib/mail/message.rb, line 1167 def body_encoding=(value) body.encoding = value end
# File lib/mail/message.rb, line 1478 def bounced? delivery_status_part and delivery_status_part.bounced? end
Returns the current boundary for this message part
# File lib/mail/message.rb, line 1507 def boundary content_type_parameters ? content_type_parameters['boundary'] : nil end
Returns the Cc value of the mail object as an array of strings of address specs.
Example:
mail.cc = 'Mikel <mikel@test.lindsaar.net>' mail.cc #=> ['mikel@test.lindsaar.net'] mail.cc = 'Mikel <mikel@test.lindsaar.net>, ada@test.lindsaar.net' mail.cc #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
Also allows you to set the value by passing a value as a parameter
Example:
mail.cc 'Mikel <mikel@test.lindsaar.net>' mail.cc #=> ['mikel@test.lindsaar.net']
Additionally, you can append new addresses to the returned Array like object.
Example:
mail.cc 'Mikel <mikel@test.lindsaar.net>' mail.cc << 'ada@test.lindsaar.net' mail.cc #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
# File lib/mail/message.rb, line 515 def cc( val = nil ) default :cc, val end
Sets the Cc value of the mail object, pass in a string of the field
Example:
mail.cc = 'Mikel <mikel@test.lindsaar.net>' mail.cc #=> ['mikel@test.lindsaar.net'] mail.cc = 'Mikel <mikel@test.lindsaar.net>, ada@test.lindsaar.net' mail.cc #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
# File lib/mail/message.rb, line 527 def cc=( val ) header[:cc] = val end
Returns an array of addresses (the encoded value) in the Cc field, if no Cc field, returns an empty array
# File lib/mail/message.rb, line 1199 def cc_addrs cc ? [cc].flatten : [] end
Returns the character set defined in the content type field
# File lib/mail/message.rb, line 1422 def charset if @header content_type ? content_type_parameters['charset'] : @charset else @charset end end
Sets the charset to the supplied value.
# File lib/mail/message.rb, line 1431 def charset=(value) @defaulted_charset = false @charset = value @header.charset = value end
# File lib/mail/message.rb, line 531 def comments( val = nil ) default :comments, val end
# File lib/mail/message.rb, line 535 def comments=( val ) header[:comments] = val end
# File lib/mail/message.rb, line 539 def content_description( val = nil ) default :content_description, val end
# File lib/mail/message.rb, line 543 def content_description=( val ) header[:content_description] = val end
# File lib/mail/message.rb, line 547 def content_disposition( val = nil ) default :content_disposition, val end
# File lib/mail/message.rb, line 551 def content_disposition=( val ) header[:content_disposition] = val end

# File lib/mail/message.rb, line 575 def content_transfer_encoding=( val ) header[:content_transfer_encoding] = val end
# File lib/mail/message.rb, line 579 def content_type( val = nil ) default :content_type, val end
# File lib/mail/message.rb, line 583 def content_type=( val ) header[:content_type] = val end
Returns the content type parameters
# File lib/mail/message.rb, line 1454 def content_type_parameters has_content_type? ? header[:content_type].parameters : nil rescue nil end
# File lib/mail/message.rb, line 1676 def convert_to_multipart text = body.decoded self.body = '' text_part = Mail::Part.new({:content_type => 'text/plain;', :body => text}) text_part.charset = charset unless @defaulted_charset self.body << text_part end
# File lib/mail/message.rb, line 587 def date( val = nil ) default :date, val end
# File lib/mail/message.rb, line 591 def date=( val ) header[:date] = val end
# File lib/mail/message.rb, line 1759 def decode_body body.decoded end

Returns the default value of the field requested as a symbol.
Each header field has a :default method which returns the most common use case for that field, for example, the date field types will return a DateTime object when sent :default, the subject, or unstructured fields will return a decoded string of their value, the address field types will return a single addr_spec or an array of addr_specs if there is more than one.
# File lib/mail/message.rb, line 1102 def default( sym, val = nil ) if val header[sym] = val else header[sym].default if header[sym] end end
Delivers an mail object.
Examples:
mail = Mail.read('file.eml') mail.deliver
# File lib/mail/message.rb, line 226 def deliver inform_interceptors if delivery_handler delivery_handler.deliver_mail(self) { do_delivery } else do_delivery end inform_observers self end
This method bypasses checking #perform_deliveries and #raise_delivery_errors, so use with caution.
It still however fires callbacks to the observers if they are defined.
Returns self
# File lib/mail/message.rb, line 243 def deliver! response = delivery_method.deliver!(self) inform_observers delivery_method.settings[:return_response] ? response : self end
# File lib/mail/message.rb, line 249 def delivery_method(method = nil, settings = {}) unless method @delivery_method else @delivery_method = Configuration.instance.lookup_delivery_method(method).new(settings) end end
returns the part in a multipart/report email that has the content-type delivery-status
# File lib/mail/message.rb, line 1474 def delivery_status_part @delivery_stats_part ||= parts.select { |p| p.delivery_status_report_part? }.first end
Returns true if the message is a multipart/report; report-type=delivery-status;
# File lib/mail/message.rb, line 1469 def delivery_status_report? multipart_report? && content_type_parameters['report-type'] =~ %r^delivery-status$/ end
Returns the list of addresses this message should be sent to by collecting the addresses off the to, cc and bcc fields.
Example:
mail.to = 'mikel@test.lindsaar.net' mail.cc = 'sam@test.lindsaar.net' mail.bcc = 'bob@test.lindsaar.net' mail.destinations.length #=> 3 mail.destinations.first #=> 'mikel@test.lindsaar.net'
# File lib/mail/message.rb, line 1181 def destinations [to_addrs, cc_addrs, bcc_addrs].compact.flatten end
# File lib/mail/message.rb, line 1494 def diagnostic_code delivery_status_part and delivery_status_part.diagnostic_code end
# File lib/mail/message.rb, line 1697 def encode! STDERR.puts("Deprecated in 1.1.0 in favour of :ready_to_send! as it is less confusing with encoding and decoding.") ready_to_send! end
Outputs an encoded string representation of the mail message including all headers, attachments, etc. This is an encoded email in US-ASCII, so it is able to be directly sent to an email server.
# File lib/mail/message.rb, line 1705 def encoded ready_to_send! buffer = header.encoded buffer << "\r\n" buffer << body.encoded(content_transfer_encoding) buffer end
# File lib/mail/message.rb, line 392 def envelope_date @envelope ? @envelope.date : nil end
# File lib/mail/message.rb, line 388 def envelope_from @envelope ? @envelope.from : nil end
# File lib/mail/message.rb, line 1490 def error_status delivery_status_part and delivery_status_part.error_status end
Returns a list of parser errors on the header, each field that had an error will be reparsed as an unstructured field to preserve the data inside, but will not be used for further processing.
It returns a nested array of [field_name, value, original_error_message] per error found.
Example:
message = Mail.new("Content-Transfer-Encoding: weirdo\r\n") message.errors.size #=> 1 message.errors.first[0] #=> "Content-Transfer-Encoding" message.errors.first[1] #=> "weirdo" message.errors.first[3] #=> <The original error message exception>
This is a good first defence on detecting spam by the way. Some spammers send invalid emails to try and get email parsers to give up parsing them.
# File lib/mail/message.rb, line 445 def errors header.errors end
Returns the filename of the attachment
# File lib/mail/message.rb, line 1775 def filename find_attachment end
# File lib/mail/message.rb, line 1486 def final_recipient delivery_status_part and delivery_status_part.final_recipient end
# File lib/mail/message.rb, line 1783 def find_first_mime_type(mt) all_parts.detect { |p| p.mime_type == mt && !p.attachment? } end
Returns the From value of the mail object as an array of strings of address specs.
Example:
mail.from = 'Mikel <mikel@test.lindsaar.net>' mail.from #=> ['mikel@test.lindsaar.net'] mail.from = 'Mikel <mikel@test.lindsaar.net>, ada@test.lindsaar.net' mail.from #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
Also allows you to set the value by passing a value as a parameter
Example:
mail.from 'Mikel <mikel@test.lindsaar.net>' mail.from #=> ['mikel@test.lindsaar.net']
Additionally, you can append new addresses to the returned Array like object.
Example:
mail.from 'Mikel <mikel@test.lindsaar.net>' mail.from << 'ada@test.lindsaar.net' mail.from #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
# File lib/mail/message.rb, line 632 def from( val = nil ) default :from, val end
Sets the From value of the mail object, pass in a string of the field
Example:
mail.from = 'Mikel <mikel@test.lindsaar.net>' mail.from #=> ['mikel@test.lindsaar.net'] mail.from = 'Mikel <mikel@test.lindsaar.net>, ada@test.lindsaar.net' mail.from #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
# File lib/mail/message.rb, line 644 def from=( val ) header[:from] = val end
Returns an array of addresses (the encoded value) in the From field, if no From field, returns an empty array
# File lib/mail/message.rb, line 1187 def from_addrs from ? [from].flatten : [] end
# File lib/mail/message.rb, line 1554 def has_attachments? !attachments.empty? end
# File lib/mail/message.rb, line 1322 def has_charset? tmp = header[:content_type].parameters rescue nil !!(has_content_type? && tmp && tmp['charset']) end
# File lib/mail/message.rb, line 1327 def has_content_transfer_encoding? header[:content_transfer_encoding] && header[:content_transfer_encoding].errors.blank? end
# File lib/mail/message.rb, line 1317 def has_content_type? tmp = header[:content_type].main_type rescue nil !!tmp end
Returns true if the message has a Date field, the field may or may not have a value, but the field exists or not.
# File lib/mail/message.rb, line 1307 def has_date? header.has_date? end
Returns true if the message has a message ID field, the field may or may not have a value, but the field exists or not.
# File lib/mail/message.rb, line 1301 def has_message_id? header.has_message_id? end
Returns true if the message has a Date field, the field may or may not have a value, but the field exists or not.
# File lib/mail/message.rb, line 1313 def has_mime_version? header.has_mime_version? end
Returns the header object of the message object. Or, if passed a parameter sets the value.
Example:
mail = Mail::Message.new('To: mikel\r\nFrom: you') mail.header #=> #<Mail::Header:0x13ce14 @raw_source="To: mikel\r\nFr... mail.header #=> nil mail.header 'To: mikel\r\nFrom: you' mail.header #=> #<Mail::Header:0x13ce14 @raw_source="To: mikel\r\nFr...
# File lib/mail/message.rb, line 417 def header(value = nil) value ? self.header = value : @header end
Sets the header of the message object.
Example:
mail.header = 'To: mikel@test.lindsaar.net\r\nFrom: Bob@bob.com' mail.header #=> <#Mail::Header
# File lib/mail/message.rb, line 402 def header=(value) @header = Mail::Header.new(value, charset) end
Returns an FieldList of all the fields in the header in the order that they appear in the header
# File lib/mail/message.rb, line 1295 def header_fields header.fields end
Provides a way to set custom headers, by passing in a hash
# File lib/mail/message.rb, line 422 def headers(hash = {}) hash.each_pair do |k,v| header[k] = v end end
Accessor for #html_part
# File lib/mail/message.rb, line 1559 def html_part(&block) if block_given? @html_part = Mail::Part.new(&block) add_multipart_alternate_header unless html_part.blank? add_part(@html_part) else @html_part || find_first_mime_type('text/html') end end
Helper to add a html part to a multipart/alternative email. If this and #text_part are both defined in a message, then it will be a multipart/alternative message and set itself that way.
# File lib/mail/message.rb, line 1583 def html_part=(msg = nil) if msg @html_part = msg else @html_part = Mail::Part.new('Content-Type: text/html;') end add_multipart_alternate_header unless text_part.blank? add_part(@html_part) end
# File lib/mail/message.rb, line 648 def in_reply_to( val = nil ) default :in_reply_to, val end
# File lib/mail/message.rb, line 652 def in_reply_to=( val ) header[:in_reply_to] = val end
# File lib/mail/message.rb, line 216 def inform_interceptors Mail.inform_interceptors(self) end
# File lib/mail/message.rb, line 212 def inform_observers Mail.inform_observers(self) end
# File lib/mail/message.rb, line 1736 def inspect "#<#{self.class}:#{self.object_id}, Multipart: #{multipart?}, Headers: #{header.field_summary}>" end
Returns whether message will be marked for deletion. If so, the message will be deleted at session close (i.e. after find exits), but only if also using the find_and_delete method, or by calling find with :delete_after_find set to true.
Side-note: Just to be clear, this method will return true even if the message hasn’t yet been marked for delete on the mail server. However, if this method returns true, it *will be* marked on the server after each block yields back to find or find_and_delete.
# File lib/mail/message.rb, line 1812 def is_marked_for_delete? return @mark_for_delete end
# File lib/mail/message.rb, line 656 def keywords( val = nil ) default :keywords, val end
# File lib/mail/message.rb, line 660 def keywords=( val ) header[:keywords] = val end
Returns the main content type
# File lib/mail/message.rb, line 1438 def main_type has_content_type? ? header[:content_type].main_type : nil rescue nil end
Sets whether this message should be deleted at session close (i.e. after find). Message will only be deleted if messages are retrieved using the find_and_delete method, or by calling find with :delete_after_find set to true.
# File lib/mail/message.rb, line 1799 def mark_for_delete=(value = true) @mark_for_delete = value end
# File lib/mail/message.rb, line 1416 def message_content_type STDERR.puts(":message_content_type is deprecated in Mail 1.4.3. Please use mime_type\n#{caller}") mime_type end
Returns the Message-ID of the mail object. Note, per RFC 2822 the Message ID consists of what is INSIDE the < > usually seen in the mail header, so this method will return only what is inside.
Example:
mail.message_id = '<1234@message.id>' mail.message_id #=> '1234@message.id'
Also allows you to set the Message-ID by passing a string as a parameter
mail.message_id '<1234@message.id>' mail.message_id #=> '1234@message.id'
# File lib/mail/message.rb, line 677 def message_id( val = nil ) default :message_id, val end
Sets the Message-ID. Note, per RFC 2822 the Message ID consists of what is INSIDE the < > usually seen in the mail header, so this method will return only what is inside.
mail.message_id = '<1234@message.id>' mail.message_id #=> '1234@message.id'
# File lib/mail/message.rb, line 686 def message_id=( val ) header[:message_id] = val end
Method Missing in this implementation allows you to set any of the standard fields directly as you would the “to”, “subject” etc.
Those fields used most often (to, subject et al) are given their own method for ease of documentation and also to avoid the hook call to method missing.
This will only catch the known fields listed in:
Mail::Field::KNOWN_FIELDS
as per RFC 2822, any ruby string or method name could pretty much be a field name, so we don’t want to just catch ANYTHING sent to a message object and interpret it as a header.
This method provides all three types of header call to set, read and explicitly set with the = operator
Examples:
mail.comments = 'These are some comments' mail.comments #=> 'These are some comments' mail.comments 'These are other comments' mail.comments #=> 'These are other comments' mail.date = 'Tue, 1 Jul 2003 10:52:37 +0200' mail.date.to_s #=> 'Tue, 1 Jul 2003 10:52:37 +0200' mail.date 'Tue, 1 Jul 2003 10:52:37 +0200' mail.date.to_s #=> 'Tue, 1 Jul 2003 10:52:37 +0200' mail.resent_msg_id = '<1234@resent_msg_id.lindsaar.net>' mail.resent_msg_id #=> '<1234@resent_msg_id.lindsaar.net>' mail.resent_msg_id '<4567@resent_msg_id.lindsaar.net>' mail.resent_msg_id #=> '<4567@resent_msg_id.lindsaar.net>'
# File lib/mail/message.rb, line 1276 def method_missing(name, *args, &block) #:nodoc: # Only take the structured fields, as we could take _anything_ really # as it could become an optional field... "but therin lies the dark side" field_name = underscoreize(name).chomp("=") if Mail::Field::KNOWN_FIELDS.include?(field_name) if args.empty? header[field_name] else header[field_name] = args.first end else super # otherwise pass it on end #:startdoc: end
Returns the content type parameters
# File lib/mail/message.rb, line 1448 def mime_parameters STDERR.puts(':mime_parameters is deprecated in Mail 1.4.3, please use :content_type_parameters instead') content_type_parameters end

# File lib/mail/message.rb, line 1412 def mime_type content_type ? header[:content_type].string : nil rescue nil end
Returns the MIME version of the email as a string
Example:
mail.mime_version = '1.0' mail.mime_version #=> '1.0'
Also allows you to set the MIME version by passing a string as a parameter.
Example:
mail.mime_version '1.0' mail.mime_version #=> '1.0'
# File lib/mail/message.rb, line 703 def mime_version( val = nil ) default :mime_version, val end
Sets the MIME version of the email by accepting a string
Example:
mail.mime_version = '1.0' mail.mime_version #=> '1.0'
# File lib/mail/message.rb, line 713 def mime_version=( val ) header[:mime_version] = val end
Returns true if the message is multipart
# File lib/mail/message.rb, line 1459 def multipart? has_content_type? ? !!(main_type =~ %r^multipart$/) : false end
Returns true if the message is a multipart/report
# File lib/mail/message.rb, line 1464 def multipart_report? multipart? && sub_type =~ %r^report$/ end
Allows you to add a part in block form to an existing mail message object
Example:
mail = Mail.new do part :content_type => "multipart/alternative", :content_disposition => "inline" do |p| p.part :content_type => "text/plain", :body => "test text\nline #2" p.part :content_type => "text/html", :body => "<b>test</b> HTML<br/>\nline #2" end end
# File lib/mail/message.rb, line 1628 def part(params = {}) new_part = Part.new(params) yield new_part if block_given? add_part(new_part) end
Returns a parts list object of all the parts in the message
# File lib/mail/message.rb, line 1512 def parts body.parts end
The #raw_envelope is the From mikel@test.lindsaar.net Mon May 2 16:07:05 2009 type field that you can see at the top of any email that has come from a mailbox
# File lib/mail/message.rb, line 384 def raw_envelope @raw_envelope end
Provides access to the raw source of the message as it was when it was instantiated. This is set at initialization and so is untouched by the parsers or decoder / encoders
Example:
mail = Mail.new('This is an invalid email message') mail.raw_source #=> "This is an invalid email message"
# File lib/mail/message.rb, line 371 def raw_source @raw_source end
# File lib/mail/message.rb, line 1751 def read if self.attachment? decode_body else raise NoMethodError, 'Can not call read on a part unless it is an attachment.' end end
Encodes the message, calls encode on all it’s parts, gets an email message ready to send
# File lib/mail/message.rb, line 1687 def ready_to_send! identify_and_set_transfer_encoding parts.sort!([ "text/plain", "text/enriched", "text/html", "multipart/alternative" ]) parts.each do |part| part.transport_encoding = transport_encoding part.ready_to_send! end add_required_fields end

You can make an new mail object via a block, passing a string, file or direct assignment.
mail = Mail.new do from 'mikel@test.lindsaar.net' to 'you@test.lindsaar.net' subject 'This is a test email' body File.read('body.txt') end mail.to_s #=> "From: mikel@test.lindsaar.net\r\nTo: you@...
mail = Mail.new("To: mikel@test.lindsaar.net\r\nSubject: Hello\r\n\r\nHi there!") mail.body.to_s #=> 'Hi there!' mail.subject #=> 'Hello' mail.to #=> 'mikel@test.lindsaar.net'
mail = Mail.read('path/to/file.eml') mail.body.to_s #=> 'Hi there!' mail.subject #=> 'Hello' mail.to #=> 'mikel@test.lindsaar.net'
You can assign values to a mail object via four approaches:
Examples:
mail = Mail.new mail['from'] = 'mikel@test.lindsaar.net' mail[:to] = 'you@test.lindsaar.net' mail.subject 'This is a test email' mail.body = 'This is a body' mail.to_s #=> "From: mikel@test.lindsaar.net\r\nTo: you@...
