Is there any chance that high memory utilization could be responsible for some of these errors? I’ve noticed recently that my memory is running anywhere from 80-85%.

Hello all!

Recently I upgraded my mail server to Ubuntu 22.04 LTS and ever since then I am periodically getting some dovecot errors like the below in my mail log. As far as I can tell, my unix perms are just fine. What is ACL/MAC?

Aug 20 14:41:58 mail dovecot: imap(user@domain.com)<56316><1NieGKPmuOdKwxVI>: Error: Mailbox INBOX: stat(/mnt/volume1/mailserver/plain/maildir/domain.com/user/dovecot.index.log) failed: Permission denied (euid=1000(austin) egid=1000(austin) UNIX perms appear ok (ACL/MAC wrong?))

And here is the listing showing the permissions for that file.

austin@mail:~$ ls -la /mnt/volume1/mailserver/plain/maildir/domain.com/user/dovecot.index.log
-rwxrwxr-- 1 austin austin 15796 Aug 20 14:41 /mnt/volume1/mailserver/plain/maildir/domain.com/user/dovecot.index.log

What in the world is causing these errors, and what can I do about them?

Thanks in advance!
