Absolutely. And it'll even be considered 'secure' since local
connections are secure.

OTOH, if you're going to the trouble to use ssh anyway, can Thunderbird
do something like a "connect command"? I use that in evolution, and mine
looks like something like this:
	ssh -C mailserver '/usr/sbin/dovecot --exec-mail imap'

where 'mailserver' really is an alias in my .ssh/config
