Dovecot debug logs rarely help with any random problems you have, they’re mostly there to find out configuration mistakes. More interesting would be to know if you see ANY error/warning messages in Dovecot logs (Fatal, Panic, Error, Warning). You’ll also see the last 1000 error messages since dovecot started with “doveadm log errors”.
