[Help-gnutls] SMTP TLS & Thunderbird

I'm trying to use GNUTLS to implement TLS functionality on an SMTP daemon I've
got. It's nearly working really well; the example in 7.4.5 was really useful.

I've implemented the code in the server to do the TLS handshake, and
everything works fine when I connect to it with gnutls-cli. Unfortunately,
when I try it with real data, using Thunderbird, it doesn't work. Handshake
fails with "Could not negotiate a supported cipher suite."

Thunderbird appears to be using OpenSSL. GNUTLS *does* work with OpenSSL,
right? If so, can anyone offer any suggestions as to what might be going on,
and how to fix it?

This is with GNUTLS 1.4.0-3ubuntu1 on Ubuntu Edgy Eft and Thunderbird
