they are. My MUA is configured to send mail out on port 465, but that's
not the point. The point is that the MTA on my workstation is not
configured to send mail to other hosts on any port besides port 25.
think cron messages delivered to a remote account. fixing the issue on
my end is trivial. that's not the point either.

who's running a server on the end of a residential comcast connection?
not me.
I disagree with you about it being a good thing. If they can change the
service that they've given me a 2 year contract for, then what's to stop
them from blocking port 80/tcp out and telling me that i have to use
their proxy, tell me i can only visit sites on port 443, or even tell me
i can only visit sites that are set up on gopher.

no doubt, but my complaint is about changing the rules in the middle of
the game.
