Is there a way to setup Exchange Server 2003 to relay emails from different port numbers? I have some users setup with pop and smtp connection because they travel. I used the standard Default Virtual Server on port 25 to do this which works great. I have some users Home ISP is now blocking port 25 from relaying so I would like to create an additional smtp server to relay using port 2525 as well. Any help on this would be great.
