vmailmgr - a package to manage virtual mailboxes and aliases

=head1 DESCRIPTION

This document describes the vmailmgr package which contains, among other
things, a virtualizing password
checking interface for qmail-pop3d.
It is intended as a drop-in replacement for the standard checkpassword
utility with several significant enhancements.

One of the goals of building this package was to provide a usable virtual
mail interface that was efficient and as fully integrated into qmail as
possible.
This means that this package attempts to use the same control files that
qmail uses to determine if a user is logging in via a virtual host.
It also implies that all programs should be compiled for two reasons:

=over 8

=item 1

Compiled code will be more efficient than code executed by an
interpreter, such as perl or java

=item 2

There is no need for an
interpreter to reside on the system once the code is compiled, eliminating
concerns that such an interpreter could be used as an exploit in itself.
