Setup exchange to relay emails on port 25 and port 2525

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.

Sure is.. just need to create a new SMTP server, and you can set that to any port you want.  Just add it under protocols, SMTP.

Once you create it, you can go into the properties of the server and modify what users can connect to it under the relay permissions.  If you want only one user to be able to use it, you can do that, or give open it to anyone.

Sorry... more specific... Exchange System Manager, Expand out your server name, then expand out protocols, then SMTP.  In there you should see the default SMTP server.  You can right click on the SMTP folder and do a new server from there.

Once you get the SMTP server added (its a short two step wizard), you will then need to go into the properties of the new server, and then go to the advanced settings button on the first tab to set the port number you want it to run on.

I am getting a connection error when I try to connect to the new smtp server on port 2525. Will exchange listen on both ports 25 and 2525?

Also when I run a port scanner on my exchange server it tells me that port 2525 is closed. Firewall is off so it looks like exchange is not listening on that port.

Yes, exchange will listen on what ever port you tell it to.  Did you go into the advanced settings of the new SMTP vitrual server you created and change the port number?  Also, did you start the new virtual server?  You should not see the white circle on the new virtual server you created.

Yes, I changed the port number and made sure the new virtual server was started.

Have you tried restarting the SMTP service itself in services?  It may need to be cycled for it to start running on that port.  Other changes to SMTP like spam filtering settings need that service to be cycled for the changes to take effect.

I know this works because I have had similar problems and set up another virtual server to run on port 25000.  In the advanced settings is the server bound to once specific IP?  Or is it set to all?  Try setting it to a specific IP if it is not already.

I restarted the smtp services with no luck. I did notice the following event log after I created the smtp server.

Virtual Server 2 SMTP server cannot read metabase key MailPickupDir.

But I did see emails in the VS2 queue folder that was waiting to be sent. II still get the smtp connection error in outlook when I try to use the new virtual server to send emails.
