=head1 NAME
qmail-queue
=head1 DESCRIPTION
This is the most common plugin used to queue incoming mails. A
variation of this plugin would maybe forward the mail via smtp.
=head1 CONFIG
It takes one optional parameter, the location of qmail-queue. This
makes it easy to use a qmail-queue replacement.
queue/qmail-queue /var/qmail/bin/another-qmail-queue
If set the environment variable QMAILQUEUE overrides this setting.
