And, in what manner, is this a surprise?

I've had them block Comcast before (and, yes, I was relaying through 
Comcast's SMTP server properly). GMail & Yahoo Mail has been a problem 
upon occasion too.

I have to drive to the North Country to fix a network. The customer was 
having some problem accessing Verizon's webmail and called Verizon 
(rather than us). Verizon had them rewire and reconfigure the network. 
The end result, they have an on-demand PPPoE connection for a single 
Windows system instead of an always-on connection for a Linux/Windows 
network. The single system on the Internet can no longer see the rest of 
the network. Verizon told them to throw out their broken router, which 
happens to be a $2000 Sonicwall VPN solution. That's the point the 
customer called us, thank the gods.

Of course, it is not a Verizon monopoly, just last week I had a 
customer, who uses Comcast's authenticated SMTP, have his email rejected 
while traveling. Comcast said that smtp.comcast.net was blacklisted. :-) 
(It was fixed within an hour, FWIW.)
