But your backup MX is "trusted" in the sense that it will not forge sender addresses, Received: lines etc. -- that's what trusted_networks basically implies. If trusted_networks etc are set correctly, SA will recognize your backup MX, and will not apply any RBL checks to it's IP address. The Mail::SpamAssassin::Conf man-page has all the dirty details, including those of internal_networks > The backup MX does NO filtering at all, it just accepts ALL mail that > has a certain destination domain and then forwards it to the Primary MX > where SA is running, SA is doing all the filtering and > white/black/grey-listing. You should ensure that connections from your backup MX are not grey/blacklisted at the MTA level (don't know whether you're already doing it, but just to mention it...). - -- Matthias -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFGzDfTxbHw2nyi/okRAq7jAKCbKv8IknFw2Nmse3l3LTszN7OyYgCfY28l XAA+s+kES1B4mbmcvK2VE24= =95OW -----END PGP SIGNATURE-----
