Well, I recommend you switch to postfix and set up TLS on port 465 (the
standard smtp over SSL submission port). If that port is blocked you can
choose another. Here are some notes I made on this setup a while back:

spend less time learning postfix than you would trying to configure
sendmail to make this one change!
