Mail::Message::Part - a part of a message, but a message by itself

Mail::Message::Part
  is a Mail::Message
  is a Mail::Reporter

my Mail::Message $message = ...;
if($message->isMultipart) {
   my Mail::Message::Part $part;
   foreach $part ($message->body->parts) {
      $part->print(\*OUT);
      my $attached_head = $part->head;
      my $attached_body = $part->body;      # encoded as read
      my $attached_body = $part->decoded;   # transfer-encoding removed
   }
}

A "Mail::Message::Part" object contains a message which is included in the body of another message. For instance attachments are parts.

READ Mail::Message FIRST. A part is a special message: it has a reference to its parent message, and will usually not be sub-classed into mail folder specific variants.

$class->build( [$message|$part|$body], @fields, %options )
Inherited, see "Constructing a message" in Mail::Message::Construct::Build
$class->buildFromBody($body, $container, $headers)
Shape a message part around a $body. Bodies have information about their content in them, which is used to construct a header for the message. Next to that, more $headers can be specified. No headers are obligatory. No extra headers are fabricated automatically. Improves base, see "Constructing a message" in Mail::Message::Construct::Build

my $multi = Mail::Message::Body::Multipart->new;
my $part  = Mail::Message::Part->buildFromBody($body, $multi);

$class->coerce( <$body|$message>, $multipart, @headers )
Transforms a $body or $message to a real message part. The $multipart refers to the parental body.

When a $body is specified, extra @headers can be supplied as well. Bodies are coerced into message parts by calling buildFromBody(). If you specify a $message residing in a folder, this message will automatically be cloned. Improves base, see "Internals" in Mail::Message

Extends "Cleanup" in Mail::Message.

$obj->DESTROY()
Inherited, see "Cleanup" in Mail::Reporter
$obj->destruct()
Message parts can not be destructed per part: only whole messages can be forcefully freed from memory. Of course, you can delete() separate parts, which only sets a flag not to write a part again. Furthermore, you may cosider rebuild() to get rit of deleted parts. Improves base, see "Cleanup" in Mail::Message

Extends "DETAILS" in Mail::Message.

Unknown alternative for the forward(include). Valid choices are "NO", "INLINE", "ATTACH", and "ENCAPSULATE". Cast by forward()
The message send() mechanism had not enough information to automatically find a mail transfer agent to sent this message. Specify a mailer explicitly using the "via" options. Cast by send()
Unknown alternative for the "include" option of reply(). Valid choices are "NO", "INLINE", and "ATTACH". Cast by reply()
Cast by read()
Fatal error: the specific $package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package. Cast by notImplemented()
The message bounce() method forwards a received message off to someone else without modification; you must specified it's new destination. If you have the urge not to specify any destination, you probably are looking for reply(). When you wish to modify the content, use forward(). Cast by bounce()
Cast by forwardAttach()
Cast by forwardEncapsulate()
Cast by forwardNo()
Cast by forwardNo()
Cast by new()
Cast by rebuild()
You may wish to construct a message to be stored in a some kind of folder, but you need to do that in two steps. First, create a normal Mail::Message, and then add it to the folder. During this Mail::Box::addMessage() process, the message will get coerce()-d into the right message type, adding storage information and the like. Cast by build()
Cast by parts()
Cast by build()
Message parts can not be destructed per part: only whole messages can be forcefully freed from memory. Consider delete() or rebuild(). Cast by destruct()
