Dashboard Mail Queue Error

PBX Version:

PBX Distro:

Asterisk Version:

For some unknown reason recently, Postfix started throwing permission errors when trying to send outgoing emails. The maillog was full of these messages:

postfix/postdrop[228829]: warning: mail_queue_enter: create file maildrop/791798.228829: Permission denied

The issue was fixed by resetting permissions:
chmod 3730 /var/spool/postfix/maildrop
Which results in:
ls -l /var/spool/postfix/
drwx-ws–T+ 2 postfix postdrop 6 Jul 16 23:53 maildrop
…which is the setting recommended by Postfix. After running fwconsole chown the permissions are unchanged from the above.

It was also noted that the Sangoma-root partition was nearly full, which may have contributed to this issue. I have now removed many obsolete recordings and log files and also expanded the disk partition so the system is now at 50% capacity.

Postfix is now operating normally with no errors in the maillog.

However on the FreePBX Dashboard, the Mail Queue is showing a flame error with the following notice:

Unknown Output from mailq:[[“postqueue:fatal:Connect to the Postfix showq service:Permission denied”],69]

Please note the Postfix is operating normally now.
I have performed fwconsole chown twice and fwconsole restart to no effect.
I have also added asterisk user to the postdrop group and restarted again, but still no effect.

Any ideas where to look next would be appreciated.
