At the moment imap.progsoc.uts.edu.au is ftoomsh which sounds right.

From ftoomsh I can do `telnet 0 imap2' and get: IMAP4rev1 v12.250 server ready

I tried `telnet 0 imap3' but that doesn't work so maybe you are trying to
connect to the wrong port (that is one possibility). You should get a
connection refused message rather than a time out.

The other possibility is that maybe the firewall is throwing away your
packets, Wim has been looking at the firewall recently and might have changed
something (that would fit with the connection timing out rather than
closing properly).

I can't get the firewall to throw away my packets though, I tried from
a home dialup and found that I connected to ftoomsh then it closed
connection cleanly and refused entry. This would most likely be to avoid
unencrypted connections going through dialup lines (we don't want passwords
to be ridiculously easy to crack). When I try the same from a few machines
round UTS I connect and get the server ready message so it seems OK for
these cases.

So I guess the question is, where are you comming from and is the connection
actually timing out or is it cleanly opening, then chucking you off?
Some imap clients may not explain the difference between a connection refused
and a connection closed and a time out so you may have to use a telnet to
try to figure out what is happening.

We probably have a system where some dialups are allowed unencrypted access
like with the telnets, I was hoping to get rid of this now that ssh is widely
available in both free and non-free forms but since no one wants to use
encrypted links maybe we can just add your dialup to the list.
