We had the same results. According to the docs, the access file is supposed
to override the RBL lookups, but it is buggy at best. Sometimes it works and
sometimes it doesn't. We took most of the RBL lookups out of sendmail and
stuck them in SpamAssassin and began tagging instead of blocking. To get the
performance up on the relay servers, we switched to the reiser file system
and put the temp dirs in ram, and setup a separate log server connected
through a second nic. We are still looking for better ways to block at least
some of the spam at the MTA level, but we are leaning towards throwing more
and more processor power at the problem and sticking to tagging.
