I think it's clear that we need MixMinion for the near future and well,
the present for everyday of people. :(

These issues should be listed in the TODO file - I'm sorry to say that
Thunderbird and the Mozilla team seems to refuse to Do The Right Thing
with the account setup wizard. The bugs on this topic are a depressing
read - it's not really possible to override this and fail closed - which
seems like an unreasonable stance...

That is to be expected, yes.

Great. So as it stands, I found the following meta-data in your email
that may be harmful to your privacy:
Date: Sun, 06 May 2012 11:52:25 +1000
Your raw email is impressive in how many systems it seems to touch - it
routes over Tor through the Noisebridge exit, it traverses some ipv6
SMTP servers and so on. There's a lot of stuff in there - can you look
through it and tell me if any of it is harmful to your privacy other
than the two lines listed above?
All the best,
