Question : Domino 7 SMTP can listen two ports at same time?

I want to setup Domino 7 to listen SMTP port 25 and 26 at the same time.
Because some outlook users need to use SMTP 26 port when they outside office.
And some users need to use SMTP port 25.
How can i do this?
Environment: Domino 7 with POP service enabled. NT Domain, outlok 2003 and outlook 2000, XP, 2007, Lotus client 7.
Many thanks.

Answer : Domino 7 SMTP can listen two ports at same time?

I don't think you can do this as a Domino server has only one entry in the server document for the SMTP port. Can you run partitioned servers on the same box, then you can set one partition up for one port and the other partitioned server can listen on the other port.
