I will be setting up a SMTP GAteway server on the DMZ, can i use a different port

I am going to setup a smtp gateway server on our DMS, should i use a different port to forward the mail inside? Is that possible? i know sometimes we change port numbers on services to mask what they are and add more security. I will be using windows 2003 server for the smtp gateway and a windows 2000 server running exchange 2000 as the smart host.
thanks. this is the first time i will have done this. We use to just use a 1 to 1 NAT through the firewall and open up SMTP to the server.
