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
Extends "METHODS" in Mail::Message.
Constructors
Extends "Constructors" in Mail::Message.
- $obj->clone(%options)
-
Inherited, see "Constructors" in Mail::Message
- $class->new(%options)
-
Create a message part. Improves base, see "Constructors" in Mail::Reporter

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, andENCAPSULATE. Cast byforward() - Error: Cannot include reply source as $include.
-
Unknown alternative for the
includeoption of reply(). Valid choices areNO,INLINE, andATTACH. Cast byreply() - 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
viaoptions. Cast bysend() - 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()
