Today I woke up to over 1100 incoming mails, all bounces from other servers. Some filthy spammer has been using my domain in their From: headers for a while now, but it was never this bad (maybe 10-20 bounces a day). So, I decided to take action, and wrote up a Perl script which filters incoming mail based on the To: and Envelope-to: headers, via a whitelist file of usernames (newline-delimited). It will also log accepts and denies to a file if you want it to.
I'll probably throw it up somewhere later.
So far, so good!
