I'm running Dovecot-1.0-stable on Solaris with Thunderbird OK, but, 
again, without SSL. Have you tried it without SSL? Can you get a packet 
trace (use Solaris "snoop" then look at it with Ethereal) or use rawlog 
(I think you have to compile support for the latter into Dovecot)?

Best Wishes,
Chris
