Hi

What's the best approach to filtering out spam at server mailbox level? I am
running FC5 and SendMail...

Best Regards

Chris

There seems to be a sisagreement on this but I would try spamasasassin.
The program is isntalled but you can find installation configuration
instructions on the web.

Since sendmail runs procmail on each messgae it receives you can use
a .procmailrc script to run spamassassin and distribute your mail
(including the spam found) in to appropriate mail boxes.
Running spamassassin using a milter has the advantage that you can reject the spam during the SMTP transaction. So in the rare case where a legitimate message is mis-identified as spam, the sender gets to know that it wasn't delivered. You can't safely do that using procmail.

Paul.

Huh! I have being doing that for years byt having .procmailrc direct
identified spam to a special file. Doesn't that do it or do I not
understand you point?

Doing this means that *you* get to see the mail identified as spam, when you look in the special file. Rejecting the message in the SMTP transaction means that the *sender* knows you didn't get the email, so they can either try resending a less-spammy message, or contacting you by other means if it's something important. No intervention needed on your part.

Oh really.... And how do you keep a joe-job from turning your system
into a spam system? Or do you mean simply 404ing the transaction?
