There's no surprise that you get the password prompt for the ssh 
session, it's the establishing of a tunnel that goes wrong.

Did you change 192.168.x.x to 127.0.0.1 and L143 to L1430? If not do it, 
and configure thunderbird to connect to localhost:1430.

If you speak IMAP you can also telnet localhost:1430 instead of 
reconfiguring thunderbird every time.

Cheers, Erik
