Hello all!

My strange permission errors in my log files seem to have disappeared. The only thing I can think of that I changed was mounting my encrypted folder without using sudo. Example “gocryptfs -allow_other cipher plain” instead of "sudo gocryptfs -allow_other cipher plain”.

Thanks to all of you for your help and suggestions!

It’s a mount partition you should check that probably it is nfs.

Good luck.

I think I may have gotten this resolved. More time and testing will tell! More details later . . .

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 <http://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 <http://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 <http://domain.com/user/dovecot.index.log>*

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

Thanks in advance!

Did you check wether your linux distribution uses SeLINUX or Apparmor ? In that case you would have to check their policy to give dovecot access to this directory.
