So all you really need to do on your SIMS server is to enable 'Relay for
Clients Only' and put your W* server's IP address as the only entry in
SIMS' Client Hosts list. As long as the SIMS server has no local accounts,
you don't need it to do anything else. Use of blacklists on the SIMS server
is superfluous because only the W* server will be allowed to relay anything
anyway. As long as you don't have any local accounts on the SIMS server
(i.e. all traffic through SIMS is relays, with no possibility of messages
being accepted for local delivery because there are no local accounts),
then all connections from any host other than the W* server will be
rejected as unauthorized third-party relay attempts, regardless of whether
or not they might be in a blacklist. If you're worried about spam being
sent from your W* server and relayed through SIMS then, for the most part,
it should be the W* server's responsibility to catch it, although it
probably wouldn't hurt to enable SIMS' Return-Path checking.
