2500 timeouts a day!

Now the load on the server is something I've never really thought of. Is
there anyway to offload any processes to another MS server as I'm
bringing one up as a failover?

You are saying that you removed bigevil.cf? How do I use surbl.org?
Isn't that an RBL? It can replace bigevil?

Is there a limit on how many SA rule files you should use?

The primary DNS for the MailScanner server is an internal DNS server on
the same LAN, this in turn forwards requests to an external DNS server
that is also on the same LAN (we host public DNS). Would it give me any
advantage to create a caching nameserver on the MailScanner server? The
queries seem to resolve pretty quick when testing with Dig.

I run RBL's via MailScanner and SA. Even though the MS RBL's timeout
sometimes, that would never cause SA to timeout, right?

One other thing. I have a blacklist with about 1500 entries in it. I'm
going to move this temporarily tonight and see if this reduces the
timeouts. My blacklist removes 300 pieces of spam per day, so I'm afraid
to remove it permanently. I tried to look on the logs to see how many of
them might be also caught by bayes, but it seems as though once an email
is blacklisted, no other checks are done.

I will also look at reducing the number of children/messages to process.

Thanks,
Max
