NAME

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

INHERITANCE

        Mail::Box::Message::Destructed
          is a Mail::Box::Message
          is a Mail::Message
          is a Mail::Reporter

SYNOPSIS

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

DESCRIPTION

       When a message folder is read, each message will be parsed into Perl structures.
       Especially the header structure can consume a huge amount of memory (message bodies can be
       moved to external temporary files).  Destructed messages have forcefully cleaned-up all
       header and body information, and are therefore much smaller.  Some useful information is
       still in the object.

       BE WARNED: once a message is destructed, it cannot be revived.  Destructing enforces
       irreversable deletion from the folder.  If you have a folder opened for read-only, the
       message will stay in that folder, but otherwise it may be deleted.

       Extends "DESCRIPTION" in Mail::Box::Message.

METHODS

       Extends "METHODS" in Mail::Box::Message.

   Constructors
       Extends "Constructors" in Mail::Box::Message.

       $obj->clone(%options)

       Mail::Box::Message::Destructed->new($message_id, %options)
           You cannot instantiate a destructed message object.  Destruction is done by calling
           Mail::Box::Message::destruct().

DIAGNOSTICS

       Error: Cannot coerce a (class) into destruction
           Only real Mail::Box::Message objects can get destructed into
           Mail::Box::Message::Destructed objects.  Mail::Message free their memory immediately
           when the last reference is lost.

       Error: Cannot include forward source as $include.
           Unknown alternative for the forward(include).  Valid choices are "NO", "INLINE",
           "ATTACH", and "ENCAPSULATE".

       Error: Cannot include reply source as $include.
           Unknown alternative for the "include" option of reply().  Valid choices are "NO",
           "INLINE", and "ATTACH".

       Error: Destructed message has no labels except 'deleted'
       Error: Destructed messages can not be undeleted
           Once a message is destructed, it can not be revived.  Destruction is an optimization
           in memory usage: if you need an undelete functionality, then you can not use
           Mail::Box::Message::destruct().

       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().

       Error: Method forwardAttach requires a preamble
       Error: Method forwardEncapsulate requires a preamble
       Error: No address to create forwarded to.
           If a forward message is created, a destination address must be specified.

       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.

       Error: No rebuild rule $name defined.
       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.

       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.

       Error: You cannot instantiate a destructed message
           You cannot instantiate a destructed message object directly.  Destruction is done by
           calling Mail::Box::Message::destruct() on any existing folder message.

       Error: You cannot take the head/body of a destructed message
           The message originated from a folder, but its memory has been freed-up forcefully by
           means of Mail::Box::Message::destruct().  Apparently, your program still tries to get
           to the header or body data after this destruction, which is not possible.
