19              $part->print(\*OUT);
20              my $attached_head = $part->head;
21              my $attached_body = $part->body;      # encoded as read

DESCRIPTION

27       A "Mail::Message::Part" object contains a message which is included in
28       the body of another message.  For instance attachments are parts.
29
30       READ Mail::Message FIRST.  A part is a special message: it has a
31       reference to its parent message, and will usually not be sub-classed
32       into mail folder specific variants.
33
34       Extends "DESCRIPTION" in Mail::Message.

91
92       Mail::Message::Part->buildFromBody($body, $container, $headers)
93           Shape a message part around a $body.  Bodies have information about
94           their content in them, which is used to construct a header for the
95           message.  Next to that, more $headers can be specified.  No headers
96           are obligatory.  No extra headers are fabricated automatically.
97

99
100            my $multi = Mail::Message::Body::Multipart->new;

407           separate parts, which only sets a flag not to write a part again.
408           Furthermore, you may cosider rebuild() to get rit of deleted parts.

425           destination.  If you have the urge not to specify any destination,
426           you probably are looking for reply(). When you wish to modify the
427           content, use forward().

436           The message send() mechanism had not enough information to
437           automatically find a mail transfer agent to sent this message.
438           Specify a mailer explicitly using the "via" options.

440       Error: No rebuild rule $name defined.
441       Error: Only build() Mail::Message's; they are not in a folder yet
442           You may wish to construct a message to be stored in a some kind of
443           folder, but you need to do that in two steps.  First, create a
444           normal Mail::Message, and then add it to the folder.  During this
445           Mail::Box::addMessage() process, the message will get coerce()-d
446           into the right message type, adding storage information and the
447           like.

449       Error: Package $package does not implement $method.
450           Fatal error: the specific package (or one of its superclasses) does
451           not implement this method where it should. This message means that
452           some other related classes do implement this method however the
453           class at hand does not.  Probably you should investigate this and
454           probably inform the author of the package.
455
456       Error: You cannot destruct message parts, only whole messages
457           Message parts can not be destructed per part: only whole messages
458           can be forcefully freed from memory. Consider delete() or
459           rebuild().
