Sounds somewhat "crazy" to me :) see, ASSP is capable of running LDAP lookups by itself and SHOULD do that btw since it *needs* to know if a given recipient address exists or not and, in case it doesn't exist, reject the message (and optionally generate spamtraps); so imHo you'd better setup ASSP to run LDAP lookups (or VRFY/RCPT checks) against "mx2" and let it work as it's designed :) With such a setup your mailflow will be the following * incoming email internet -> ASSP -> mx1 -> mx2 -> local mailbox (Note: the LDAP or VRFY recipient checking should be handled by ASSP against mx2) * outgoing email local mailbox -> mx2 -> ASSP -> mx1 -> internet any external user willing to send email will fall onto the "incoming" flow but will authenticated so that ASSP will see the session as "trusted" Once you'll have such a setup (with LDAP working) try sending an email (through exchange) to the "assp.local" address, then use the exchange message tracking to check the "path" for the message and also check the ASSP maillog.txt to look at entries related to the message ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
