It did. Port 25 is rejected in the default policy, but 587 and 465 are not
any longer:

root at esse:~# grep '\*:465' /var/lib/tor/cached-descriptors|wc -l
296
root at esse:~# grep '\*:587' /var/lib/tor/cached-descriptors|wc -l
297
root at esse:~# grep '\*:25' /var/lib/tor/cached-descriptors|wc -l
1127
root at esse:~# 

If you're using TLS on port 587 then some information will be sent in plain
text for the exit node to sniff. The welcome banner, and the EHLO
request/response. If you can use SSL on connect on port 465, then nothing
is sent in plain text.

Other than DNS leaks, you need to make sure Thunderbird doesn't leak any
other information in the EHLO or the headers when sending mail.
