I am using Snow Leopard Server's mail service to relay mail through my ISP's mail relay over port 25. However, they requested that I start using port 587. How can I change the port used?

When inserting the name of the host through which to relay outbound mail, add brackets around the name, then add a colon followed by the port number.
smtp.example.com
becomes [smtp.example.com]:587
