OK Minor correction, I see that SimpleFilter is a POP3 proxy
service and not a client program.  In other words, it is a
centralized server through which POP traffic passes.  Please
still do:

1.  Whitelist common whitehats.  There's no point in
querying the SURBL nameservers for yahoo.com millions
of times a day, right?


2.  Cache.  If you are using DNS lookups make sure it's caching
locally at least somewhat.
