Topic: IMAP Error | Missing +r perm | Dovecot

===System Information===
- iRedMail version: 0.9.8
- Linux Distro: Ubuntu 16.04 Xenial Xerus LTS (64x)
- Mail Account Backend: MySQL
- Web server: Apache
- Mail accounts are not managed by iRedMail Pro

===Problem===
Hey guys,
I could only find one place where the topic was discussed but was never answered. It seems like a really easy fix, but all I've done to it has not worked. Basically, the IMAP setup can't create a mailbox and it wants +r perms to the /var/run/dovecot/dict folder. I've done that plus some but it doesn't seem to work. I've also tried restarting dovecot, and the entire server machine to no avail.

I've already attempted adding the necessary permissions, setting group change to it, but it hasn't done anything. Much appreciation would be had if someone can sort out what might be wrong.

Is uid 2000 and gid 2000 assigned to system user "vmail"?

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

UID was, but the GID wasn't, so I assigned it as such and restarted Dovecot.

Now it's giving me this error (From IMAP log):

Re: IMAP Error | Missing +r perm | Dovecot

uid of vmail user is 5000, please set it to 2000 instead.

Everything is set to 2000 now.

Here's the same console report with the updated UID value.

I'll also include the IMAP log here for another connection attempt:

Re: IMAP Error | Missing +r perm | Dovecot

I just found you placed the mailbox under /home/ directory. this might cause problem because /home/<user> is always set to 0700, and some services running by systemd also have "ProtectHome=yes" setting to refuse other applications write to /home/<user> directory.

Anyway, try this command first, let's see how it works:

chmod 0755 /home/pldyn_network

Also please double check all parent directories of '/home/pldyn_network/mailsys/vmail/vmail1/' is accessible by user/goup: vmail:vmail.
