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.

METHODS

Constructors

$obj->clone(OPTIONS)

See "Constructors" in Mail::Message

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.
