I am really getting tired of adding in entries into the access
file, and writing email filters (in thunderbird) for patterns
dumping spammers into the trash - and yet - I am still forced
to review the trash for entries that should not have been trashed.  
Seems like a real chore and a losing proposition...

What do admins of sendmail use, besides spamassasin?

Thanks!

one approach is to use the black hole filters, confgure them for sendmail
and that will catch a lot of bad addresses..

Hmm...  I reviewed this, added the FEATURE entry but
unfortunately it is missing the corresponding mc file:

m4:sendmail.mc:198: cannot open `/usr/share/sendmail-cf/feature/rbl.m4': No such file or directory

Where can I get this mc file, do you know?

try 'yum install sendmail-cf'   ???
