2.3.17 broken on CentOS8 / bug

Wed Nov 3 14:56:10 EET 2021

You are correct that the problem is not fully fixed yet. It, however, only affects practically cases where you do

doveadm -c /path <command>

We will fix it properly in a future release, now it has been fixed to work as it used to before, so no new regression is introduced.

I had no time to investigate this any longer thand 2 hours with 2.3.17 installed as this is a production server and I need the email access. I also did not find anything adressable in the logs.
