my personal favorite, a one liner to set up an email tunnel on a non-privileged port: ssh -f username@mymailserver.com -L 2000:mymailserver.com:25 -N

  Why not connect to mymailserver.com's port 25 directly?

    Because plenty of ISP's will block outgoing traffic on port 25.

    Another reason is in case you don't want your access ISP reading your outbound mail (in the case where the smtpd doesn't support STARTTLS).
