Hi, Im running mandrake 7.2 with sendmail 8.11 and apache 1.3.12 (I know it's old, but its a bit tricky to upgrade that server at the moment). We received some complaints that our server had been used to spam, and when I looked at the sendmail logs, it shows an email being sent nearly every second but it says "from=apache" and I havent got a clue how they're doing this. There are a few websites on that server that have formmail (perl) and php contact pages that have the to field already specified, could this be the cause?
Also, could it be that its because I'm running old versions of apache and or sendmail? Whats the best way to stop this person spamming through my server?
