<font face="Lato">Hello,<br>
<br>
tonight my dovecot upgraded to 2.3.17 and completely broke on
recent CentOS 8 installation.<br>
<br>
I found the service in status <br>
<br>
[root@riot ~]# systemctl status dovecot<br>

<br>
This seems to be like a bug as no configuration was changed by me
in the middle of the night.<br>
I recall there were similar errors/bug reports in the past were it
seemed it was managesieve but wasn't, people had some
misconfigurations in the dovecot.conf. I did not change my
dovecot.conf since April.<br>
But maybe here it is a pigeonhole issue.<br>
<br>
As I did not find any reason for it I changed the repo and
downgraded to 2.3.16-2 now and it runs without any flaws, like all
the time before. 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.<br>
