Hello,
I'm trying to move a dovecot mail server from a remote Cpanel VPS to my
site.
I've set up the dovectot to my knowledge, but as soon as I try to
authenticate, I got a crash:

Thhe only reference I've fount to this error is that it seems to be an
issue in 2.3.17, but I have 2.3.21 version, so I think there's something
in my config. I've also hhave a bunch of old maildirs and I tried to do
a force-resync on 'em, but that didn't help.
Here's my config:

here's my obfuscated users passdb file:
===Cut===

e...@kimlab.link:{PLAIN}XXXXXXXXX::::::
===Cut===
I'm totally open to any ideas.
I can provide coredumps as well, but I tend to think that's something
obvious since I have very little experience with dovecot.
Thanks.
Eugene.
