New csf v2.34

New feature:

  • Added a new option (beta for now) PT_SMTP. This option will check for outgoing connections to port 25, ecluding root, exim and mailman. The purpose of the feature is to log SMTP connections if you believe you have a spammer on the server who is bypassing exim to send out spam emails – this is traditionally a very difficult form of spam to track down. The option currently logs relevant process information to lfd.log to avoid an email alert flood.
