 Hi!

 You could try updating to 2.2.28, if possible. I believe this bug is
 fixed in 2.2.28, with
 https://github.com/dovecot/core/commit/1fd44e0634ac312d0960f39f9518b71e08248b65

It seems we still have some of these unsquashed, we'll look into this
further.

2017-04-06 Thread Christian Balzer 

Hello Aki, Timo,

according to git this fix should be in 2.2.27, which I'm running, so I
guess this isn't it or something else is missing.
See:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=859700

Christian
