Comment (by sukhbir):

 Interesting, thanks for reporting. We don't try (we can't) to pretend that
 TorBirdy was used, since that is trivial to find out from the header
 itself using the exit node information, and also possibly from the
 message-ID header.

 What we do prevent is leaking specific user agent information, such as the
 Thunderbird version. So I am not fully convinced if we should fix this,
 what do you think?
