I am experiencing a consistent panic while using doveadm sync on Dovecot
v2.4.2. The panic occurs during a synchronization attempt between two
servers. It appears that the sync panics when entering in a
.Junk.Something folder.
Any idea? I attach the log lines and my configuration
Any help would be appreciated
