I would like to configure Sendmail to use a couple of blacklists in order to reduce the amount of spam received. I found some instructions athttp://list.cobalt.com/pipermail/cobalt-developers/2003-April/039145.html whichinvolved modifying the file cobalt.mc by adding a couple of FEATURE commands, recompiling it with m4 and using the result to replace the sendmail.cf file.I tried this and it did reduce the amount of spam quite a lot. Unfortunately, it also killed all the mailing lists on my server. Anyone posting a message to anyof the mailing lists got a 550 "unknown user" response. So I reverted to my original sendmail.cf file. I guess this means that the original sendmail.cf file was not derived fromcobalt.mc. The new sendmail.cf was actually shorter than the old one, so I guessthe old one must have some extra stuff to handle mailing lists correctly. Does anyone know how a solution?
-snip-Assuming you followed the instructions quoted in the archive mail then you should be able to perform a:
diff spamblock.cf sendmail.cf.orig Look through the differences for anything related to majordomo.Having done the same as you before though I would guess the following line is missing from your new /etc/mail/sendmail.cf
O AliasFile=/etc/mail/aliases.majordomo If you still have the newly created sendmail.cf then search through for: # location of alias file O AliasFile=/etc/mail/aliases Edit it manually (vi or pico etc) so it now reads: # location of alias file O AliasFile=/etc/mail/aliases O AliasFile=/etc/mail/aliases.majordomoOtherwise suggest reading through - http://bluebird.sinauer.com/~morse/cobalt/dnsbl.html
Even with the bluebird instructions you'll probably need to run the diff command and then add the O AliasFile=/etc/mail/aliases.majordomo since those instructions don't take into account a server with majordomo configured.
