NAME
    Email::Abstract - Unified interface to mail representations

SYNOPSIS
      my $message = Mail::Message->read($rfc822)
                    || Email::Simple->new($rfc822)
                    || Mail::Internet->new([split /\n/, $rfc822])
                    || ...;

      my $subject = Email::Abstract->get_header($message, "Subject");
      Email::Abstract->set_header($message, "Subject", "My new subject");

      my $body = Email::Abstract->get_body($message);
      Email::Abstract->set_body($message, "Hello\nTest message\n");

      $rfc822 = Email::Abstract->as_string($message);

      my $mail_message = Email::Abstract->cast($message, "Mail::Message");

DESCRIPTION
    "Email::Abstract" provides module writers with the ability to write
    representation-independent mail handling code. For instance, in the
    cases of "Mail::Thread" or "Mail::ListDetector", a key part of the code
    involves reading the headers from a mail object. Where previously one
    would either have to specify the mail class required, or to build a new
    object from scratch, "Email::Abstract" can be used to perform certain
    simple operations on an object regardless of its underlying
    representation.

    "Email::Abstract" currently supports "Mail::Internet", "MIME::Entity",
    "Mail::Message", "Email::Simple" and "Email::MIME". Other
    representations are encouraged to create their own "Email::Abstract::*"
    class by copying "Email::Abstract::EmailSimple". All modules installed
    under the "Email::Abstract" hierarchy will be automatically picked up
    and used.

METHODS
  get_header($obj, $header)
    This returns the value or list of values of the given header.

  set_header($obj, $header, @lines)
    This sets the $header header to the given one or more values.

  get_body($obj)
    This returns the body as a string.

  set_body($obj, $string)
    This changes the body of the email to the given string.

  as_string($obj)
    This returns the whole email as a string.
