Mail::Box::Dir::Message(3)

NAME
Mail::Box::Dir::Message - one message in a directory organized folder

INHERITANCE
 Mail::Box::Dir::Message
   is a Mail::Box::Message
   is a Mail::Message
   is a Mail::Reporter

 Mail::Box::Dir::Message is extended by
   Mail::Box::MH::Message
   Mail::Box::Maildir::Message

SYNOPSIS
 my $folder = new Mail::Box::MH ...
 my $message = $folder->message(10);

DESCRIPTION
A "Mail::Box::Dir::Message" is a base class for one message in a directory organized folder; each message is stored in a separate file. There are no objects of type "Mail::Box::Dir::Message", only extensions are allowed to be created.

At the moment, three of these extended message types are implemented:

•   Mail::Box::MH::Message

    which represents one message in a Mail::Box::MH folder. MH folders are very, very simple.... and hence not sophisticated nor fast.

•   Mail::Box::Maildir::Message

    which represents one message in a Mail::Box::Maildir folder. Flags are kept in the message's filename. It is stateless, so you will never loose a message.

•   Mail::Box::Netzwert::Message

    which represents one message in a Mail::Box::Netzwert folder. As advantage, it stores pre-parsed information in the message file. As disadvantage: the code is not GPLed (yet).

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

DIAGNOSTICS

Error: Cannot coerce a $class object into a $class object
Error: Cannot create parser for $filename.
    For some reason (the previous message have told you already) it was not possible to create a message parser for the specified filename.

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: Cannot write message to $filename: $!
    When a modified or new message is written to disk, it is first written to a temporary file in the folder directory. For some reason, it is impossible to create this file.

Error: Failed to move $new to $filename: $!
    When a modified or new message is written to disk, it is first written to a temporary file in the folder directory. Then, the new file is moved to replace the existing file. Apparently, the latter fails.

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: Unable to read delayed body.
    For some reason, the header of the message could be read, but the body cannot. Probably the file has disappeared or the permissions were changed during the progress of the program.

Error: Unable to read delayed head.
    Mail::Box tries to be lazy with respect to parsing messages. When a directory organized folder is opened, only the filenames of messages are collected. At first use, the messages are read from their file. Apperently, a message is used for the first time here, but has disappeared or is unreadible for some other reason.

Error: coercion starts with some object
