That should probably be the same for all Thunerbird users as well.

If you can already connect using Thunderbird, you must
have an entry for submission and/or submissions/smtps
(i.e., port 587 and/or 465) in /etc/postfix.master.cf,
you just need to override the smtpd_recipient_restrictions
or smtpd_relay_restrictions parameters there to permit
SASL-authenticated users t osend mail whereever they
smtps inet n - y - - smtpd
submission inet n - y - - smtpd

with canonical or generic address rewriting:
http://www.postfix.org/ADDRESS_REWRITING_README.html#generic (outgoing only)
Any parameter changes that need to be added can be
added to the service declaration in master.cf using -o
But since this is only for "select users", it probably
makes more sense for those users to just set their
correct from address in Thunderbird (unless I've
