How do I point outgoing email from exchange through a nonexchange box with separate IP address

Posted on 2007-11-19
Last Modified: 2010-03-06
I am running Exchange 2003 with a Front end and Back end server, all of which is behind a firewall which nat's to the outside.  We would like to test an antispam solution which basically is a separate non-exchange box, also behind the firewall.  Is there a way to point my outgoing email from exchange through this IP address.  As my exchange servers have traditionall talked directly with any external email servers (through the firewall), I am now not sure how to implement this.  The purpose of this is to allow the antispam solution the ability to whitelist/autoadd outgoing email addresses so that they aren't caught on the way back.

Create SMTP connector & add that Box's IP as Smart Host. 25 port of that port must be open.

yes just edit the smtp conector from dns to smart host and put the ip address inside [] or use a FQDN

Use IP address; because if DNS server (must be AD DNS) is down - outgoing mail will stop!!
