## 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}[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) }

### 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 )

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')

parse( str )

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"

### Public Instance methods

[]( key )

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"

[]=( key, val )

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

accept( strategy )
add_date()
add_message_id( fqdn = nil )
attachment?(part)
attachments()
base64_decode()

Returns the result of decoding the TMail::Mail object body without altering the current body

base64_decode!()

Convert the Mail object‘s body into a Base64 decoded email returning the modified Mail object

base64_encode()

Return the result of encoding the TMail::Mail object body without altering the current body

base64_encode!()

Convert the Mail object‘s body into a Base64 encoded email returning the modified Mail object

bcc( default = nil )

Returns who the email bcc‘d as an Array of email addresses as opposed to an Array of TMail::Address objects which is what Mail#to_addrs returns

Example:

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

bcc=( *strs )

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

Example:

     mail.bcc #=>  ["mikel@abc.org", "mikel@xyz.org"]

bcc_addrs( default = nil )

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

If the "Bcc:" field does not exist, will return nil by default or the value you pass as the optional parameter.

Example:

     mail = TMail::Mail.new
     mail.bcc_addrs #=> nil
     mail.bcc_addrs([]) #=> []
     mail.bcc = "Mikel <mikel@me.org>, another Mikel <mikel@you.org>"
     mail.bcc_addrs #=>  [#<TMail::Address mikel@me.org>, #<TMail::Address mikel@you.org>]

bcc_addrs=( arg )

Destructively set the to field of the "Bcc:" 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.bcc = "Mikel <mikel@me.org>, another Mikel <mikel@you.org>"
     mail.bcc_addrs #=>  [#<TMail::Address mikel@me.org>, #<TMail::Address mikel@you.org>]

     mail.cc_addrs #=>  [#<TMail::Address mikel@me.org>, #<TMail::Address mikel@you.org>]

charset( default = nil )

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.charset #=> "UTF-8"

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

charset=( str )

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"

reply_to_addrs( default = nil )

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

If the "Reply-To:" field does not exist, will return nil by default or the value you pass as the optional parameter.

Example:

     mail = TMail::Mail.new
     mail.reply_to_addrs #=> nil
     mail.reply_to_addrs([]) #=> []
     mail.reply_to = "Mikel <mikel@me.org>, another Mikel <mikel@you.org>"

reply_to_addrs=( arg )

Destructively set the to value of the "Reply-To:" header to equal the passed in argument.

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

     mail.sender = "Mikel <mikel@me.org>"
     mail.sender #=>  "mikel@me.org"

sender=( str )

Destructively sets the "Sender:" field to the passed string (which should be a valid email address)
