NAME
Mail::Folder::Maildir - A maildir folder interface for Mail::Folder.WARNING: This code is in alpha release. Expect the interface to change.
SYNOPSIS
"use Mail::Folder::Maildir;"DESCRIPTION
This module provides an interface to the maildir folder mechanism.The maildir folder format is the preferred folder mechanism for the qmail mail transport agent. It uses directories as folders and files as messages. It also provides separate directories for new and current messages. One of the most distinguishing features of the "maildir" format is that it accomplishes it's job without the need for file locking, so it's better equipped to deal with things like nfs mounts and the like.
More information about qmail is available from "http://pobox.com/~djb/qmail.html".
