Most of these issues do not seem to be server issues.
POP.... Receiving (i.e. getting your mail?) That is what POP is for.
IMAP & POP may have sending hidden somewhere in there protocol, but SMTP
is designed for sending. Not accessing POP from outside is the
firewall/proxy issue. Your admins way of saying he is security conscious.
SMTP.... Many places just disable outside SMTP relay access try using
your ISP's SMTP server. His way of dealing with spam security. This may
not be a proxy issue try telneting to port 25. When you telnet double
check the MX host you should be going to.
IMAP.... I don't know what this issue is. I wish more admins supported
it since it is much better than POP. I can't say it is a proxy issue
since you say it just does not work at all after connecting, but it is
connecting? Try telnet on this one as well.
FTP.... Proxy issue? Perhaps it is not ftp, but upload & download via http.
As for security, some of the non-http things are probably more secure
given all the scripts in IIS's http, but then he is using MS to begin
with so there is no security mind really in him.
When you say everything is being squashed through port 80 that is when
you try to connect to the outside world, and who knows what things
(sites/protocals/speeds) are restricted.
Telneting will often tell you the versions and settings. Read the RFC's
-- don't know if MS will tell you the settings.

supports anything. The POP settings for receiving somehow works (the proxy is probably set up to
not allow pop to the outside).

Something weird they're doing between the proxy and mail server, and possible what's happening on
the outside of the proxy, probably is messing up the actual outgoing SMTP. Or at least that was
the half-baked answer I got from the admin.

use across the board here: NT4 servers. Very few, if anything, is on Win2K. Except the lab I work
at (my supervisor - and the computer science chairman - is a marketing/MS-brainwashee, so I'm not
allowed to use anything but windows crap): we use Win2K there for one domain, NT4 for another just
so people can learn about both. Who knows.

support/doesn't support well enough what they're using. Therefore, SMTP works inside when
authentication is turned off, but doesn't work on the outside. IMAP isn't set up right, or if it
is, Evolution doesn't support the auth. type needed. POP3, again, works on the inside, like
everything else, but it isn't allowed on the outside.
