Re: Why is _incoming_ port 25 blocked?
Well, sir, I am, indeed, speaking in generalities; based on my direct experience of two ISPs (SBC/AT&T and Sonic.net, LLC), as well as indirect knowledge of the policies of a handful of other ISPs. And both offer static IP addresses, with open access to most ports (that I know of, though I don't need, so haven't tested, the NetBIOS ports.
If getting a static IP address is not an option for you, though it is offered by CenturyLink, then I am truly sorry that I can't offer any other advice. Just the observation that port 25 is widely blocked in both directions on residential, dynamic IP services.
