# TMail::Mail

## Mail Class

Accessing a TMail object done via the TMail::Mail class. As email can be fairly complex creatures, you will find a large amount of accessor and setter methods in this class!

Most of the below methods handle the header, in fact, what TMail does best is handle the header of the email object. There are only a few methods that deal directly with the body of the email, such as base64_encode and base64_decode.

### Using TMail inside your code

The usual way is to install the gem (see the README on how to do this) and then put at the top of your class:

    require 'tmail'

You can then create a new TMail object in your code with:

    @email = TMail::Mail.new

Or if you have an email as a string, you can initialize a new TMail::Mail object and get it to parse that string for you like so:

    @email = TMail::Mail.parse(email_text)

You can also read a single email off the disk, for example:

    @email = TMail::Mail.load('filename.txt')

Also, you can read a mailbox (usual unix mbox format) and end up with an array of TMail objects by doing something like this:

    # Note, we pass true as the last variable to open the mailbox read only
    mailbox = TMail::UNIXMbox.new("mailbox", nil, true)
    @emails = []
    mailbox.each_port { |m| @emails << TMail::Mail.new(m) }

### Constants

ALLOW_MULTIPLE

  header

FIELD_ORDER
NOSEND_FIELDS
USE_ARRAY

### Attributes

port[R]

Provides access to the port this email is using to hold it's data

Example:

    mail = TMail::Mail.parse(email_string)
    mail.port
    #=> #<TMail::StringPort:id=0xa2c952>

### Public Class Methods

load( fname ) click to toggle source

Opens an email that has been saved out as a file by itself.

This function will read a file non-destructively and then parse the contents and return a TMail::Mail object.

Does not handle multiple email mailboxes (like a unix mbox) for that use the TMail::UNIXMbox class.

Example:

    mail = TMail::Mail.load('filename')

    # File lib/tmail/mail.rb, line 98
    def load( fname )
      new(FilePort.new(fname))
    end

Also aliased as: load_from, loadfrom
load_from( fname ) click to toggle source
Alias for: load
loadfrom( fname ) click to toggle source
Alias for: load
parse( str ) click to toggle source

Parses an email from the supplied string and returns a TMail::Mail object.

Example:

    require 'rubygems'; require 'tmail'
    email_string =<<HEREDOC
    To: mikel@lindsaar.net
    From: mikel@me.com
    Subject: This is a short Email

    Hello there Mikel!

    HEREDOC
    mail = TMail::Mail.parse(email_string)
    #=> #<TMail::Mail port=#<TMail::StringPort:id=0xa30ac0> bodyport=nil>
    mail.body
    #=> "Hello there Mikel!\n\n"

    # File lib/tmail/mail.rb, line 122
    def parse( str )
      new(StringPort.new(str))
    end

### Public Instance Methods

[]( key ) click to toggle source

Returns a TMail::AddressHeader object of the field you are querying. Examples:

    @mail['from']  #=> #<TMail::AddressHeader "mikel@test.com.au">
    @mail['to']    #=> #<TMail::AddressHeader "mikel@test.com.au">

You can get the string value of this by passing "to_s" to the query: Example:

    @mail['to'].to_s #=> "mikel@test.com.au"

    # File lib/tmail/mail.rb, line 247
    def []( key )
      @header[key.downcase]
    end

Also aliased as: fetch
[]=( key, val ) click to toggle source

Allows you to set or delete TMail header objects at will. Examples:

    @mail = TMail::Mail.new
    @mail['to'].to_s       # => 'mikel@test.com.au'
    @mail['to'] = 'mikel@elsewhere.org'
    @mail['to'].to_s       # => 'mikel@elsewhere.org'
    @mail.encoded          # => "To: mikel@elsewhere.org\r\n\r\n"
    @mail['to'] = nil
    @mail['to'].to_s       # => nil
    @mail.encoded          # => "\r\n"

Note: setting mail[] = nil actually deletes the header field in question from the object, it does not just set the value of the hash to nil

    # File lib/tmail/mail.rb, line 270
    def []=( key, val )
      dkey = key.downcase

      if val.nil?
        @header.delete dkey
        return nil
      end

      case val
      when String
        header = new_hf(key, val)
      when HeaderField
        ;
      when Array
        ALLOW_MULTIPLE.include? dkey or
                raise ArgumentError, "#{key}: Header must not be multiple"
        @header[dkey] = val
        return val
      else
        header = new_hf(key, val.to_s)
      end
      if ALLOW_MULTIPLE.include? dkey
        (@header[dkey] ||= []).push header
      else
        @header[dkey] = header
      end

      val
    end

            next if field.empty?
            strategy.header_name canonical(name)
            field.accept strategy
            strategy.puts
          end
          strategy.puts

      set_addrfield 'bcc', arg
    end

body=( str ) click to toggle source

    # File lib/tmail/mail.rb, line 463
    def body=( str )
      # Sets the body of the email to a new (encoded) string.
      #
      # We also reparses the email if the body is ever reassigned, this is a performance hit, however when
      # you assign the body, you usually want to be able to make sure that you can access the attachments etc.
      #
      # Usage:
      #
      #  mail.body = "Hello, this is\nthe body text"
      #  # => "Hello, this is\nthe body"
      #  mail.body

Destructively sets the "Cc:" field to the passed array of strings (which should be valid email addresses)

Example:

    mail = TMail::Mail.new
    mail.cc = ["mikel@abc.com", "Mikel <mikel@xyz.com>"]
    mail.cc #=>  ["mikel@abc.org", "mikel@xyz.org"]
    mail['cc'].to_s #=> "mikel@abc.com, Mikel <mikel@xyz.com>"

    # File lib/tmail/interface.rb, line 318

      set_string_array_attr 'Cc', strs
    end

cc_addrs( default = nil ) click to toggle source

Return a TMail::Addresses instance for each entry in the "Cc:" field of the mail object header.

      if h = @header['cc']
        h.addrs
      else
        default
      end
    end

cc_addrs=( arg ) click to toggle source

Destructively set the to field of the "Cc:" header to equal the passed in string.

TMail will parse your contents and turn each valid email address into a TMail::Address object before assigning it to the mail message.

Example:

    mail = TMail::Mail.new
    mail.cc = "Mikel <mikel@me.org>, another Mikel <mikel@you.org>"
    mail.cc_addrs #=>  [#<TMail::Address mikel@me.org>, #<TMail::Address mikel@you.org>]

    def cc_addrs=( arg )
      set_addrfield 'cc', arg
    end

charset( default = nil ) click to toggle source

Returns the character set of the email. Returns nil if no encoding set or returns whatever default you pass as a parameter - note passing the parameter does NOT change the mail object in any way.

Example:

    mail = TMail::Mail.load("path_to/utf8_email")
    mail.charset #=> "UTF-8"

    mail = TMail::Mail.new
    mail.charset #=> nil
    mail.charset("US-ASCII") #=> "US-ASCII"

    # File lib/tmail/interface.rb, line 864
    def charset( default = nil )
      if h = @header['content-type']
        h['charset'] or default
      else
        mime_version_charset || default
      end
    end

charset=( str ) click to toggle source

Destructively sets the character set used by this mail object to the passed string, you should note though that this does nothing to the mail body, just changes the header value, you will need to transliterate the body as well to match whatever you put in this header value if you are changing character sets.

Example:

    mail = TMail::Mail.new
    mail.charset #=> nil
    mail.charset = "UTF-8"
    mail.charset #=> "UTF-8"

    # File lib/tmail/interface.rb, line 893
    def charset=( str )
      if str
        if h = @header[ 'content-type' ]
          h['charset'] = str
        else
          store 'Content-Type', "text/plain; charset=#{str}"
        end
      end
      str
    end

    mail.content_type #=> nil
    mail.content_type([]) #=> []
    mail = TMail::Mail.load("../test/fixtures/raw_email")

message_id=( str ) click to toggle source

Destructively sets the message ID of the mail object instance to the passed in string

Invalid message IDs are ignored (silently, unless configured otherwise) and result in a nil message ID. Left and right angle brackets are required.

Be warned however, that calling mail.ready_to_send will overwrite whatever value you have in this field with an automatically generated unique value.

If you really want to set your own message ID and know what you are doing per the various RFCs, you can do so with the enforced_message_id= command

Example:

    mail = TMail::Mail.new
    mail.message_id = "<348F04F142D69C21-291E56D292BC@xxxx.net>"
