I feel your pain. Blocking port 25 is such a lame 'anti-spam' technique. But
it can be a blessing in disguise.

Utilizing an alternative port is one approach.... but by far the easiest
solution is to have your clients use their ISP's SMTP server for outgoing
mail. They will continue to set their POP account to your server. Earthlink
is particularly bad about this, among others.
