If you've used telnet and it works, giving a response from the smtp server
you're expecting, then you don't have the problem. The network can't easily
determine what program you're using to initiate connections, it just sees a
connect to port 25 and doesn't care whether it's you playing with telnet or
your mail program sending mail.

To me it means you can use ssh to connect to a machine on their network and
get a shell prompt where you can run standard unix commands. I have one,
it's really useful at times.
