Yeah, I'm using a local rbldnsd on each server too and using the RBL list
dnsbl-1.uceprotect.net. I like that one because it automatically clears out
blocked IP's after 7 days if they don't keep hitting their spam traps.
Julian mentioned using Sendmail itself to filter. I just am not that familiar
with sendmail, so I have some reading to do. :-)
I might setup a new server to test as an upgrade to the existing setup. This
way I can use SA and see how it affects the system load and still use the
latest and greatest versions. Right now I'm just instructing users how to
setup Outlook rules to delete those messages, but that's very tedious.
Thanks for all the help.
