During the monthly meeting I realized that my analysis was actually
pretty wrong all the way. Thanks everybody for correcting me!

So here is a draft of the security advisory, please review and comment:

https://tails.boum.org/blueprint/claws_mail_leaks_plaintext_to_imap/

I'd like to publish it on Thursday morning (or early afternoon) to have
it visible over the week-end before the release.

I pointed upstream to it on
http://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=2965#c9.

On Thursday, I'll also integrate this in the Claws Mail doc and fix
#9159 at last.
