open your dovecot.conf file and add the below to the bottom and restart dovecot/postfix

nano /etc/dovecot/dovecot.conf
service stats {
unix_listener stats-reader {
user = vmail
group = vmail
mode = 0660
}

unix_listener stats-writer {
    user = vmail
    group = vmail
    mode = 0660
}

}

service dovecot restart && service postfix restart;
service dovecot status && service postfix status;

Force queue delivery via flush
postqueue -f

Check current queue
postqueue -p

Hopefully its working again.

I have had to add that to a bunch of cyberpanel servers to correct that same issue.
