class Mail::Message

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 Mail::Message.new method, or just Mail.new

A Message object by default has the following objects inside it:

Per RFC2822

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).

Attributes

delivery_handler[RW]

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 its own private do_delivery method.

perform_deliveries[RW]

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

raise_delivery_errors[RW]

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

Making an email

You can make an new mail object via a block, passing a string, file or direct assignment.

Making an email via a block

mail = Mail.new do |m|
  m.from 'mikel@test.lindsaar.net'
  m.to 'you@test.lindsaar.net'
  m.subject 'This is a test email'
  m.body File.read('body.txt')
end

mail.to_s #=> "From: mikel@test.lindsaar.net\r\nTo: you@...

If may also pass a block with no arguments, in which case it will be evaluated in the scope of the new message instance:

mail = Mail.new do
  from 'mikel@test.lindsaar.net'
  # …
end

Making an email via passing a string

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'

Making an email from a file

mail = Mail.read('path/to/file.eml')
mail.body.to_s #=> 'Hi there!'
mail.subject   #=> 'Hello'
mail.to        #=> 'mikel@test.lindsaar.net'

Making an email via assignment

You can assign values to a mail object via four approaches:

  • Message#field_name=(value)

  • Message#field_name(value)

  • Message#=(value)

  • Message#=(value)

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@...
# File lib/mail/message.rb, line 107
def initialize(*args, &block)
  @body = nil
  @body_raw = nil
  @separate_parts = false
  @text_part = nil
  @html_part = nil
  @errors = nil
  @header = nil
  @charset = self.class.default_charset
  @defaulted_charset = true

  @smtp_envelope_from = nil
  @smtp_envelope_to = nil

  @perform_deliveries = true

  @delivery_handler = nil

  @delivery_method = Mail.delivery_method.dup

  @transport_encoding = Mail::Encodings.get_encoding('7bit')

  @mark_for_delete = false

  if args.flatten.first.respond_to?(:each_pair)
    init_with_hash(args.flatten.first)
  else
    init_with_string(args.flatten[0].to_s)
  end

  # Support both builder styles:
  #
  #   Mail.new do
  #     to 'recipient@example.com'
  #   end
  #
  # and
  #
  #   Mail.new do |m|
  #     m.to 'recipient@example.com'
  #   end
  if block_given?
    if block.arity.zero?
      instance_eval(&block)
    else
      yield self

Public Instance Methods

<=>(other) click to toggle source

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 334
def <=>(other)
  if other.nil?
    1
  else
    self.date <=> other.date
  end
end
==(other) click to toggle source

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 373
def ==(other)
  return false unless other.respond_to?(:encoded)

  if self.message_id && other.message_id
    self.encoded == other.encoded
  else
    dup.tap { |m| m.message_id = '<temp@test>' }.encoded ==
      other.dup.tap { |m| m.message_id = '<temp@test>' }.encoded
  end
end
[](name) click to toggle source

Allows you to read an arbitrary header

Example:

mail['foo'] = '1234'
mail['foo'].to_s #=> '1234'
# File lib/mail/message.rb, line 1334
def [](name)
  header[Utilities.underscoreize(name)]
end
[]=(name, value) click to toggle source

Allows you to add an arbitrary header

Example:

mail['foo'] = '1234'
mail['foo'].to_s #=> '1234'
# File lib/mail/message.rb, line 1316
def []=(name, value)
  if name.to_s == 'body'
    self.body = value
  elsif name.to_s =~ /content[-_]type/i
    header[name] = value
  elsif name.to_s == 'charset'
    self.charset = value
  else
    header[name] = value
  end
end
action() click to toggle source
# File lib/mail/message.rb, line 1558
def action
  delivery_status_part and delivery_status_part.action
end
add_charset() click to toggle source

Adds a content type and charset if the body is US-ASCII

Otherwise raises a warning

# File lib/mail/message.rb, line 1472
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.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"
      warn(warning)
    end
    if @charset
      header[:content_type].parameters['charset'] = @charset
    end
  end
end
add_content_transfer_encoding() click to toggle source

Adds a content transfer encoding

# File lib/mail/message.rb, line 1487
def add_content_transfer_encoding
  header[:content_transfer_encoding] ||= body.default_encoding
end
add_content_type() click to toggle source

Adds a content type and charset if the body is US-ASCII

Otherwise raises a warning

# File lib/mail/message.rb, line 1465
def add_content_type
  header[:content_type] = 'text/plain'
end
add_date(date_val = '') click to toggle source

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 1448
def add_date(date_val = '')
  header['date'] = date_val
end
add_file(values) click to toggle source

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 its 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'

# File lib/mail/message.rb, line 1757
def add_file(values)
  convert_to_multipart unless self.multipart? || Utilities.blank?(self.body.decoded)
  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
  end
  self.attachments[basename] = filedata
end
add_message_id(msg_id_val = '') click to toggle source

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 1438
def add_message_id(msg_id_val = '')
  header['message-id'] = msg_id_val
end
add_mime_version(ver_val = '') click to toggle source

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 1458
def add_mime_version(ver_val = '')
  header['mime-version'] = ver_val
end
add_part(part) click to toggle source

Adds a part to the parts list or creates the part list

# File lib/mail/message.rb, line 1701
def add_part(part)
  if !body.multipart? && !Utilities.blank?(self.body.decoded)
    @text_part = Mail::Part.new('Content-Type: text/plain;')
    @text_part.body = body.decoded
    self.body << @text_part
    add_multipart_alternate_header
  end

  self.body << part
end

end
attachment() click to toggle source

Returns the attachment data if there is any

# File lib/mail/message.rb, line 1918
def attachment
  @attachment
end
attachment?() click to toggle source

Returns true if this part is an attachment, false otherwise.

# File lib/mail/message.rb, line 1913
def attachment?
  !!find_attachment
end
attachments() click to toggle source

Returns an AttachmentsList object, which holds all of the attachments in the receiver object (either the entire email or a part within) and all of its 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 1626
def attachments
  parts.attachments
end
bcc( val = nil ) click to toggle source

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 <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']

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'

default( sym, val = nil ) click to toggle source

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.

This method bypasses checking perform_deliveries and raise_delivery_errors, so use with caution.

It still however fires off the interceptors and calls the observers callbacks if they are defined.

Returns self

# File lib/mail/message.rb, line 267
def deliver!
  inform_interceptors
  response = delivery_method.deliver!(self)
  inform_observers
  delivery_method.settings[:return_response] ? response : self

# File lib/mail/message.rb, line 1566
def error_status
  delivery_status_part and delivery_status_part.error_status
end
errors() click to toggle source

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 471
def errors
  header.errors

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).
