Hello dovecot-users,
we're running Debian 7.9 with dovecot from Stephan Bosch's repository: deb http://xi.rename-it.nl/debian/ oldstable-auto/dovecot-2.2 main
Starting with dovecot 2.2.20-1 build 28, we suddenly discovered that some mails (to be locally delivered) "got stuck". dovecot's log revealed messages like the following one:

All dovecot builds newer than 2.2.20-1~auto+26 show the same behaviour.
Is there anything we can do?
