This isn't surprising, or entirely unwarrented as broadband
providers have major problems with machines running the Microsoft
Virus, Windows, owned by outsiders being used for spamming,
attacks on other networks, etc.

We generally set up our customers who're on Comcast or other
non-commercial broadband networks to send/receive via our servers
on a port other than 25 which avoids their incoming and outgoing
blocks.  Many major ISPs also block the dynamic residential IP
ranges so getting e-mail out of Comcast and similar accounts can
be a problem even if outgoing port 25 isn't being blocked, so
this, in conjunction with SMTP-AUTH, eliminates that problem.
