Can anyone tell me the best way to filter out the Sircam worm from going through our mail server using Sendmail-8.9.3-10 on a RH 6.2 system. Please be gentle, not too familiar with Sendmail. I've read about rules in sendmail.cf but don't quite understand what its talking about. Also reading O'Reilly's Sendmail but its circa 8.8. Thanks C
