apt dist-upgraded my mail server today on debian sid und it was the first time since eons that "unstable" hit me.

dovecot upgrade was a complete clusterfuck. Everything back to working now, but ffs did dovecot screw up their config handling.

Somehow, the storage setting of 'maildir' got reverted to 'mbox'. dovecot then had several processes at 100% cpu and mail.log was going crazy with errors.

Is it hard to create a `dovecot.storage' file in the inbox to detect config mistmaches?💁🏻‍♂️
