SYNOPSIS

 See Mail::Message::Body, plus

 if($body->isMultipart) {
    my @attachments = $body->parts;
    my $attachment3 = $body->part(2);
    my $before      = $body->preamble;

DESCRIPTION

READ Mail::Message::Body FIRST. This manual-page only describes the extentions to the default body functionality.

The body (content) of a message can be stored in various ways. In this manual-page you find the description of extra functionality you have when a message contains attachments (parts).

METHODS

• boundary => STRING

  Seperatory to be used between parts of the message. This seperator must be unique in case the message contains nested multiparts (which are not unusual). If <undef>, a nice unique boundary will be generated.

• epilogue => BODY

  The text which is included in the main body after the final boundary. This is usually empty, and has no meaning.

• parts => ARRAY-OF-(MESSAGES|BODIES)

  Specifies an initial list of parts in this body. These may be full MESSAGES, or BODIES which transformed into messages before use. Each message is coerced into a Mail::Message::Part object.

  MIME::Entity and Mail::Internet objects are acceptable in the list, because they are coerceable into Mail::Message::Part's. Values of undef will be skipped silently.

• preamble => BODY

  The text which is included in the body before the first part. It is common use to include a text to warn the user that the message is a multipart. However, this was useful in earlier days: most mail agents are very capable in warning the user themselves.

Example:

 my $intro = Mail::Message::Body->new(data => ['part one']);
 my $pgp   = Mail::Message::Body->new(data => ['part three']);

 my $body  = Mail::Message::Body::Multipart->new
   ( boundary => time . '--it-s-mine'
   , parts    => [ $intro, $folder->message(3)->decoded, $pgp ]
   );

encode OPTIONS

Encode the body. An encode on a multipart body is recursive into each part. New bodies will be created if any of the parts is encoded.

 OPTION            DESCRIBED IN         DEFAULT
 charset           Mail::Message::Body  undef
 mime_type         Mail::Message::Body  undef
 transfer_encoding Mail::Message::Body  undef

preamble

Returns the preamble (the text before the first message part --attachment), The preamble is stored in a BODY object, and its encoding is derived from the multipart header.

epilogue

Returns the epilogue (the text after the last message part --attachment), The preamble is stored in a BODY object, and its encoding is derived from the multipart header.

parts

In LIST context, the current list of parts (attachments) is returned, In SCALAR context the length of the list is returned, so the number of parts for this multiparted body. This is normal behavior of Perl.

Examples:

 print "Number of attachments: ", scalar $message->body->parts;

 foreach my $part ($message->body->parts) {
     print "Type: ", $part->get('Content-Type');
 }

part INDEX

Returns only the part with the specified INDEX. You may use a negative value here, which counts from the back in the list.

Example:

 $message->body->part(2)->print;

boundary [STRING]

Returns the boundary which is used to separate the parts in this body. If none was read from file, then one will be assigned. With STRING you explicitly set the boundary to be used.

attach MESSAGES|BODIES

Attach a list of MESSAGES to this multipart. A new body is returned. When you specify BODIES, they will first be translated into real messages. MIME::Entity and Mail::Internet objects may be specified too. In any case, the parts will be coerced into Mail::Message::Part's.

stripSignature OPTIONS

Removes all parts which contains data usually defined as being signature. The MIME::Type module provides this knowledge. A new multipart is returned, containing the remaining parts. No OPTIONS are defined yet, although some may be specified, because this method overrules the stripSignature method for normal bodies.
