Mail::Qmail::Filter and its submodules are designed to help you filter incoming e-mails when using qmail as MTA. You should use it like so: 1. Write a frontend script to configure your filters 2. In the run file for your qmail-smtpd instance, e.g. /var/qmail/supervise/qmail-smtpd/run, export QMAILQUEUE=path_to_your_frontend_script In each filter, you may do various things: - examine and change envelope data (RFC5321.MailFrom and recipients) - examine and modify the e-mail message (header and/or body) - "reject" e-mails (or defer them)
