After doing a bit more research, it looks like it's failing because Thunderbird doesn't prompt to accept the self-signed certificate during the "auto config" part of the setup, so just falls back to using port 143. Although I think it's still using TLS on 143. I'm really hoping someone can help me to clarify more specifically what's going on here. Thanks, Alex
