Mail::Message::Dummy(3)

NAME
Mail::Message::Dummy - a placeholder for a missing messages

INHERITANCE
 Mail::Message::Dummy
   is a Mail::Message
   is a Mail::Reporter

SYNOPSIS

DESCRIPTION
Dummy messages are used by modules which maintain ordered lists of messages, usually based on message-id. A good example is Mail::Box::Thread::Manager, which detects related messages by scanning the known message headers for references to other messages. As long as the referenced messages are not found inside the mailbox, their place is occupied by a dummy.

Be careful when using modules which may create dummies. Before trying to access the header or body use isDummy() to check if the message is a dummy message.

Extends "DESCRIPTION" in Mail::Message.

DIAGNOSTICS

Error: Cannot coerce a $class object into a $class object
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: Message-Id is required for a dummy.
    A dummy message occupies the place for a real message. When a dummy is created, the id of the message which place it is holding must be known.

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 take the head/body of a dummy message
    Dummy messages are place-holders in message threads: the thread detected the existence of the message, because it found the message-id in a Reply-To or References field, however it did not find the header and body of the message yet. Use isDummy() to check whether the thread node returned a dummy or not.

Error: coercion starts with some object
