Hi, I've enabled client certificate authentication for imap and managesieve. When I use Thunderbird with the sieve plugin it tries to login, but times out. Initially I reported this to the sieve plugin, but we came to the conclusion that it managesieve is misbehaving. https://github.com/thsmi/sieve/issues/94 Thunderbird (win10-64) 52.4.0 (32bit) Sieve 0.2.3k Dovecot (Ubuntu 16.04.3 LTS)
