I'm on qwest.net currently, and 25 outbound is open; haven't tested
inbound.  Also confirming open inbound on 22, 53, 80, 443, and 8080.
Unlike other ISPs like Comcast, Qwest's terms of service explicitly
allow running servers on your residential connection, so even if you
did find something closed you should be able to get it opened by just
asking.
