How can we initiate port forwarding outside of balsa.
In my experience, I initiate a port forwarding as a side effect of a remote
command which is generally 'sleep 5'. The port forwarding will be available
only 5 seconds but if you connect to this port during this 5 seconds, then
SSH will close the connection as soon as nobody use it.
This not-permanent port forwarding looks good to me for a remote smtp in a
MUA. 
I can't find a to do this outside of balsa.
