Sory I guess I did not explain myself properly. I have an exchange server 192.168.0.X in I have a Dlink Router 192.168.0.1 (internet gateway) I have EFW 192.168.0.3 (firewall for dmz and other servers also acts as a primary gateway and it's default route is 192.168.0.1 ) I also have other networks behind EFW for lab purposes and another firewall going out through another ISP (which has nothing to do with the problem).
Currently my Dlink router forwards incoming port 25 to EFW (192.168.0.3). it processes scan etc and forwards mail to Exchange mail server after it's been cleaned. So far so good everything is good. Currently all mail going out of my exchange server or any mail going out of the protected networks behind EFW MUST go through the exchange server as a smart host because I cannot get postfix to connect to my isp's SMTP server Via Port 587 with authentication.. So My ISP smtp server will act as a relay providing that the connection established to it uses my account and connection is on 587. Again inbound smtp traffic goes as follows 1. Internet SMTP sending server 2. Dlink forward port 25 to EFW 3. Efw Clean smart hosts to exchange server 4. Exchange (has mailboxes) Curent Outgoing traffic 1. Internal EFW network relays all mail to exchange server on port 25 2. Exchange uses ISP SMTP server on port 587 with authentication as a relay server What I want to change is outgoing flow would change to 1. Internal EFW network to EFW postfix SMTP 2. EFW postfix TO ISP on port 587 with authentication as a smart host (authentication never changes as it is my isp account) The reason I want to do this is to get proper statistics from efw as far as outgoing SMTP messages. As well as being able to monitor mail going out. To my isp via ssh, Hope this clears up the confusion. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Warasin Sent: November 22, 2006 8:47 PM To: [email protected] Subject: Re: [Efw-user] Postfix SMTP Authentication. hi Eric F.
