Uh no ! let's refer to http://i47.tinypic.com/oi574w.jpg (I created it by loading the original scheme I sent to Fritz time ago and "tailoring" it for this particular case :D) Now, let's say the public IP is 123.45.67.89 and that's the IP on which ASSP is listening (on port 25 btw) The posfix server is instead listening on 10.100.100.11:25 and is configured so that the local domains emails will be forwarded to 192.168.1.1:25 which is the Exchange server sitting on the LAN so, incoming email will hit 123.45.67.89:25 where ASSP is listening, ASSP will check incoming emails destination addresses (either using LDAP or VRFY/RCPT) against 192.168.1.1 and will proxy (smtpdest) such emails to 10.100.100.11.:25 where postfix is listening Good incoming emails will then be received by postfix which, due to config will route them to 192.168.1.1:25 that is the LAN Exchange srv Outgoing emails from LAN will be sent by users to the exchange srv the latter will then send them to 10.100.100.10:25 that is, the ASSP relayport ASSP will proxy such connections to 10.100.100.11:25 (posfix again) which will then proceed routing the emails toward the destination MX need more :) ? ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
