Thanks for all the responses.
The simplest approach in my situation seems to be the XPI one, where users can install an XPI into Thunderbird and get a template that requires only entering username and password.
Haven't figured how to put the CA certificate that Dovecot uses for SSL IMAP into the XPI for installation into Thunderbird's certificate store, but things are definitely improving :-).
