Erm, not quite. Its' not that kind of blocking. To prevent users from
running a webserver, they block *incoming* port 80. Outgoing port 80 is
still open. And besides; when your browser calls up a web page, your
computer and the server will agree on a higher port to communicate on.

Blocking outgoing SMTP (Except through the ISP's own mailservers) just
makes sense; otherwise sysadmins are spending half their day dealing
with customers with trojaned and virus-infected machines (even forcing
users to use the ISP's mailserver doesn't fix that. The viruses and
trojans will use Outlook's configured SMTP server to crank out spam.)

What ISP Are you on in Michigan? I know Comcast isn't blocking any
ports down there....
