I wonder whether tsocks could be distributed with Thunderbird, and a TBB
style startup used to load the libraries and force Thunderbird through
Tor that way?

I didn't see the Message ID as harmful, but I'm more than happy to be
educated on this front. I do see the timezone leakage as a problem. I've
had a look through Thunderbird's settings and can't see anything to
indicate that this is stored within the settings so I imagine that this
comes from system. If it's controlled through the environment then it
may be able to be set before running, again maybe through a TBB style
My only other immediate concern is how Thunderbird identifies itself to
the SMTP server during the EHLO. Claws mail provides a dialogue to show
what it's doing, and also allows you to specify what it is that is
reported to the other end. I'm not sure what Thunderbird says, but it's
likely that it is the local hostname.
