When infected hosts sending out spam got to be a gigantic plague, it became common for ISPs to block port 25 to cut down on the amount of spam they were forwarding.
I seriously doubt that your ISP will be willing to change their port blocks. They will most likely say something about "blah, blah, security best practice."
Yeah, I got tired trying to explain to the tech rep at my ISP about what I wanted so I just added a smtp port to postfix. Now everything works. Thanks to everybody who responded. Randy
