Well, actually, it does. Every broadband network in the US
currently blocks outgoing port 25 connections from retail customers.
Unfortunately, that's not entirely true. (Very) recent direct-to-MX spam
from Comcast customers:
Well, it's supposed to be blocked, according to people I've talked to
at Comcast and T-W as recently as a week ago. I can believe that they
have configuration problems on a networks of that size.
fairly certain that none of these folk block port 25 on their business
customer links.
As I said above, retail customers. Business customers get static IPs and
generaly no blocking.
