I've worked at places where inbound _and_ outbound traffic was
restricted to 22, 80, and 443 unless you were running an officially
recognized server. Yes... even 53 - you got DNS via local proxy or
not at all. Don't even ask for 25; you can't come up with a valid
justification why you should be allowed to open an SMTP port on some
external host. Environments like these make problem resolution more
difficult, but there you are.

The Internet used to have a number of useful
features that it no
longer does today -- for example, the finger and talk protocols. These
protocols no longer exist on the Internet, mostly due to valid security reasons.
Hmm, that's an interesting assertion:
apophis$ which finger
/bin/finger
apophis$ which talk
/bin/talk
...looks to me like they're still there.
