My router's public IP address is static. So that is not a problem.
But per other replies on  this list, it sounds like
a complicated puzzle to solve.
I have a dyndns name. and it maps onto my router's static IP
address. But I think at&t is blocking port 25.
I will have to talk to them and see if they will open it up.
I really need a tutorial on how I can accomplish this when
my sendmail machine is on a LAN.
