I'm not certain it's the same problem, but I also recently had a problem
using SSH to connect to certain machines. It seems that the cause was
that some time recently ssh changed so that it's reverse socket
(probably not the right term, the port that it connects to on your
machine to form a socket to port 22 on the other machine) connects to a
priveleged port (below 1024 or something). On my machine, these ports
were firewalled.

Sorry, that's probably a really bad description. The solution for me was
to use the -P option on ssh (Don't allocate a privileged port). This may
possibly be your ssh problem if you have a firewall. Don't know about
your smtp and telnet problems though.
