Overview

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:

  • A Header object which contains 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.

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).

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
     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@...

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@...

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object

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>'

Instance Attribute Details

#delivery_handlerObject

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.

178
179
# File 'lib/mail/message.rb', line 177

def delivery_handler
  @delivery_handler
end

#perform_deliveriesObject

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

def perform_deliveries
  @perform_deliveries
end

#raise_delivery_errorsObject

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

Instance Method Details

#<=>(other) ⇒ Object

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]

def <=>(other)
  if other.nil?
    1
  else
    self.date <=> other.date
  end
end

#==(other) ⇒ Object

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

#add_date(date_val = '') ⇒ Object

It will preserve any date you specify if you do.

def add_date(date_val = '')
  header['date'] = date_val
end

#add_file(values) ⇒ Object

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'

#add_message_id(msg_id_val = '') ⇒ Object

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.

#attachmentsObject

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.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"

#errorsObject

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.
