need to set up exchange 2003 to receive mail on a diffrent port, then deliver itt on standard port

Hi, here is the situation. I have a customer that uses exchange 2003 with GFI pop2exchange so that the server pops the mail from the real mail server, then smart hosts it to their ISP be delivered. They just moved offices for the summer.
Their new ISP will not allow them to smart host, nor will they allow you to connect to any other servers on port 25.
So my thought is to use my exchange 2003 server to relay the mail for them, in order to do this, I created a new virtual smtp server, but I do not know how to get this server to receive mail on a different port, I want it to receive mail on port 4545, and then relay it out to the internet on port 25.
Can someone help me please?
