A while back I setup a helo.regexp file. I have changed it around a
bit. I'm trying to stop e-mail that is sent to/from the same e-mail
address but not my system. The idea was if they are sending mail to
themselves from my ip address. It would be blocked.
Example from my test server:
/^webserv\.idahofur\.com$/ 550 Don't use my own hostname
/^216\.201\.76\.183$/ 550 Don't use my own IP address
/^[0-9.]+$/ 550 Your software is not RFC 2821 compliant
/^[0-9]+(\.[0-9]+){3}$/ 550 Your software is not RFC 2821 compliant
Example from my log:
