I think this is what you want:

-L port:host:hostport
        Specifies that the given port on the local (client) host is to be
        forwarded to the given host and port on the remote side.

So the syntax would be something like

ssh ... -L 1024:smtp.knology.com:22 your_home_machine

and then set Tbird to use localhost:1024.

Adjust to taste.
