net_connect_unix(/var/run/dovecot/stats-writer) failed: Perm)

Hi,

I have done a new install using tutorial https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/

I have created a new email address on this new server using domain mydomain.com

To test email, I am sending email from myolddomain.com & get following error as Mail Delivery notification;
<me@mydomain.com>: delivery via dovecot: delivered via dovecot

service (lda(me@mydomain.com,)Error:

net_connect_unix(/var/run/dovecot/stats-writer) failed: Perm)

May I request how to resolve this

Thanks

 

Try this: Append new settings below in /etc/dovecot/dovecot.conf, then restart dovecot service and try again.

service stats {
unix_listener stats-reader {
user = vmail
group = vmail
mode = 0660
}

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