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:

gluck@kimlab.link:{PLAIN}XXXXXXXXX:::::: emz@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.
