So what is the status on sending email through SSL ports? can it be done? I cant get gmail to work. I then tried comcast which uses port 587 and I cant get it to work either? how are you guys sending emails?

I didn't think stunnel would work with email. I haven't tried it. But typically the initial connection is plaintext, and then SSL/TLS is negotiated after the client queries the SMTP server for its capabilities. Unless stunnel makes a special provision for SMTP, I doubt it will work.
I don't know what you're running stunnel on, but if it's a unix box of some sort, you can just configure postfix as a local relay. This is what I do.
The Stunnel source code is not a complete product -- you still require a functioning SSL library such as OpenSSL or SSLeay in order to compile stunnel. This means that stunnel can support whatever (and only) that which your SSL library can, without making any changes in the Stunnel code.
Other considerations are a server based email forwarding that can handle SSL.
It works fine. I use it with my Elk. SSL doesn't care what is carried through it. You have it backwards, SSL is negotiated first, then once a tunnel is established the protocol running over it is negotiated.

SSL is *not* negotiated first in the case of port 25 or 587.
Wow I've got a lot to learn.
From stunnel.org:

I'm stuck way back at getting stunnel working on a PC on my LAN.
