NAME

6       Mail::Box::Message::Destructed - a destructed message
7

INHERITANCE

9        Mail::Box::Message::Destructed
10          is a Mail::Box::Message
11          is a Mail::Message
12          is a Mail::Reporter
13

SYNOPSIS

15        $folder->message(3)->destruct;
16

DESCRIPTION

18       When a message folder is read, each message will be parsed into Perl
19       structures.  Especially the header structure can consume a huge amount
20       of memory (message bodies can be moved to external temporary files).
21       Destructed messages have forcefully cleaned-up all header and body
22       information, and are therefore much smaller.  Some useful information
23       is still in the object.
24
25       BE WARNED: once a message is destructed, it cannot be revived.
26       Destructing enforces irreversable deletion from the folder.  If you
27       have a folder opened for read-only, the message will stay in that
28       folder, but otherwise it may be deleted.

434           Once a message is destructed, it can not be revived.  Destruction
435           is an optimization in memory usage: if you need an undelete
436           functionality, then you can not use Mail::Box::Message::destruct().
437
438       Error: Method bounce requires To, Cc, or Bcc
439           The message bounce() method forwards a received message off to
440           someone else without modification; you must specified it's new
441           destination.  If you have the urge not to specify any destination,
442           you probably are looking for reply(). When you wish to modify the
443           content, use forward().
444
445       Error: Method forwardAttach requires a preamble
446       Error: Method forwardEncapsulate requires a preamble
447       Error: No address to create forwarded to.
448           If a forward message is created, a destination address must be
449           specified.
450
451       Error: No default mailer found to send message.
452           The message send() mechanism had not enough information to
453           automatically find a mail transfer agent to sent this message.
454           Specify a mailer explicitly using the "via" options.
455
456       Error: No rebuild rule $name defined.
457       Error: Only build() Mail::Message's; they are not in a folder yet
458           You may wish to construct a message to be stored in a some kind of
459           folder, but you need to do that in two steps.  First, create a
460           normal Mail::Message, and then add it to the folder.  During this
461           Mail::Box::addMessage() process, the message will get coerce()-d
462           into the right message type, adding storage information and the
463           like.
464
465       Error: Package $package does not implement $method.
466           Fatal error: the specific package (or one of its superclasses) does
467           not implement this method where it should. This message means that
468           some other related classes do implement this method however the
469           class at hand does not.  Probably you should investigate this and
470           probably inform the author of the package.
471
472       Error: You cannot instantiate a destructed message
473           You cannot instantiate a destructed message object directly.
474           Destruction is done by calling Mail::Box::Message::destruct() on
475           any existing folder message.
476
477       Error: You cannot take the head/body of a destructed message
478           The message originated from a folder, but its memory has been
479           freed-up forcefully by means of Mail::Box::Message::destruct().
480           Apparently, your program still tries to get to the header or body
481           data after this destruction, which is not possible.
