You don't mention several important things someone would need to answer this question fully. 1. Are you running a real mailserver that needs to send/receive mail to the outside world? If not then just block port 25 incoming. If yes, then configure some UCE (unsolicited commercial email) rules on sendmail (assuming this what you have since you didn't say) and/or consider using another mailserver with easier configured security (since you're probably not a sendmail wizard). I suggest qmail or Postfix, which I use. 2. Are you the recipient of spam or is your box being used as a relay? This shouldn't happen in the default configuration any longer I believe. Either check the Handbook online for sendmail configuration. 3.
