=head1 NAME Mail::Qmail::Queue::README - Overview of Mail::Qmail::Queue =head1 SYNOPSIS C is a small collection of modules to help with talking to L and/or writing replacements for it. It also contains some handy command-line tools for testing C or its replacements. Writing C replacements is a popular way to replace parts of the functionality of the functionality of qmail (L). Because of qmail's modular style, it's easy to swap out individual components to change their behavior. This is commonly done with Bruce Guenter's QMAILQUEUE patch (L), also included in netqmail (L). This patch lets you override the standard C program by setting the environment variable C. It can also be done by renaming the original C, installing your script in its place, and having your script call the renamed C to inject the message. =head1 MODULES =over 4 =item L Easy-to-use module for sending and receiving messages. =item L Receive the envelope of a message. =item L Receive the body of a message. =item L Send a message body and envelope. =item L Utilities for handling errors. =back =head1 UTILITIES These utilities are useful for debugging and testing. =over 4 =item L Test a C replacement. =item L Dump the information sent to a C replacement. =back =head1 BUGS By convention, Perl modules start with an upper-case letter. Therefore, this module is called C, even though that's not the proper capitalization for C.
