Mail::Server - Base class for email servers in MailBox


   is a Mail::Reporter

 Mail::Server is extended by


 my $server = Mail::Server::IMAP4->new($msg);
 my $server = Mail::Server::POP3->new($msg);


This module is a place-holder, logical in the class hierarchy. On the moment, no full server has been implemented, but some parts of IMAP4 exist.

* Labels

Labels are flags which come with a message. Usually: old, seen, replied, flagged, and trashed.

The folder-types differ how they store label information. Mbox folders use the Status and X-Status fields, MH folders keep a seperate labels file called .mh_sequences, and Maildir folders put the labels in the name of the file.

Keeping the labels right is quite complicated. The `[X-]Status' header lines are only immediately updated with Mbox messages which will cause them to be written. Those lines are ignored for MH and Maildir, however updated when a new version of such a message has to be written to file.

The reason behind the MH/Maildir way of storing labels is pure performance: labels are often needed. Opening each message to see how the labels are set is cheap for Mbox, which has to read the whole folder on opening anyway, but terribly expensive for directory origanized folders (as MH and Maildir) which need to take every single message from a separate file.

Often used labels: draft to be transmitted trashed to be deleted flagged selected current last used replied a reponse message was constructed seen handled by the user old existence of message seen by user in the previous opening of the folder.


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.
