NAME

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

INHERITANCE

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

SYNOPSIS

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
   }
}

DESCRIPTION

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.

Extends "DESCRIPTION" in Mail::Message.

METHODS

Constructors

Extends "Constructors" in Mail::Message.

$obj->clone(%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);

Cleanup

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

DETAILS

Extends "DETAILS" in Mail::Message.

DIAGNOSTICS

Error: Cannot include forward source as $include.

Unknown alternative for the forward(include). Valid choices are NO, INLINE, ATTACH, and ENCAPSULATE. Cast by forward()

Error: Cannot include reply source as $include.

Unknown alternative for the include option of reply(). Valid choices are NO, INLINE, and ATTACH. Cast by reply()

Error: Method bounce requires To, Cc, or Bcc

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()

Error: Method forwardAttach requires a preamble

Cast by forwardAttach()

Error: Method forwardEncapsulate requires a preamble

Cast by forwardEncapsulate()

Error: No address to create forwarded to.

If a forward message is created, a destination address must be specified. Cast by forward()

Error: No default mailer found to send message.

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()

Error: No rebuild rule $name defined.

Cast by rebuild()

Error: Only build() Mail::Message's; they are not in a folder yet

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()

Error: Package $package does not implement $method.

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()

Error: You cannot destruct message parts, only whole messages

Message parts can not be destructed per part: only whole messages can be forcefully freed from memory. Consider delete() or rebuild(). Cast by destruct()
