Use alternate SMTP port

We have a POP/SMTP user whose home ISP will not allow port 25 connections to an external mail server. Can I configure Domino to accept SMTP on an alternate port – without disturbing existing port 25 traffic on the Domino server?

Subject: I don’t think domino can do this, but some router/firewall might be able to.

Subject: TZO.com and others have services to help with this

Subject: SMTP and SSL on port 465

Domino can be set up to accept or deliver mail on SSL port 465.
