I wonder if you are relying on secondary groups? If you are, using service imap { extra_groups = somegroup } can help. Also you could try service imap { executable = /usr/bin/strace -o /tmp/imap -f -ff /usr/lib/dovecot/imap } might be useful Aki On 06/07/2024 16:08 EEST Joan Moreau via dovecot <dovecot@dovecot.org> wrote: Moved from smb3 to sshfs to test same problem, only dovecot is complaining On Sat, 2024-07-06 at 21:04 +0800, Joan Moreau wrote: archlinux x64 no selinux activated On Sat, 2024-07-06 at 13:53 +0200, John Fawcett via dovecot wrote: Hi Joan not sure what OS you're using, so just a guess: but maybe this is selinux related or something similar. When it's the OS providing the error code to dovecot, it's very unlikely to be anything in dovecot itself.

But the error is coming from kernel, so not much Dovecot can do about it. Maybe try turning on some debugging in your server to see what is going on?

I am getting the following error : Error: pread (/ net/.../ storage/ dovecot.map.index.log) failed: Permission denied (euid=1004 (mailusers) egid=12 (mail) UNIX perms appear ok (ACL/ MAC wrong?)) How to resolve that ? Thank you This seems to be some kind of smb3 ACL problem, check permissions on the server?
