Good afternoon, I don't have programming skills so I'd like to ask for help:
I get a lot of spam where the sender uses a whole /24 Subnet as mail
relay, the helo uses the pattern
mx{last-octet-of-ip}.domainname.net
so it could be blocked using the check_spamhelo plugin, but to do that
this plugin would need a small change as it only works with hostnames.
Can somebody give me help ?
