There is a reasonably serious problem with dovecot security: <> which has been made public since June 21. It does require a man-in-the-middle attack, so it is not that easy to exploit, but it is pretty serious as it breaches credentials.

I have created a ticket in trac for the maintainers (as well as this message here) as I did know where I should inform the maintainers.
