postfwd - Postfix firewall daemon
- Description:
postfwd is written in perl to combine complex postfix restrictions in a ruleset
similar to those of the most firewalls. The program uses the postfix policy
delegation protocol to control access to the mail system before a message has
been accepted (please visit http://www.postfix.org/SMTPD_POLICY_README.html for
more information). It allows you to choose an action (e.g. reject, dunno) for a
combination of several smtp parameters (like sender and recipient address, size
or the client's TLS fingerprint).
