Now add the postfix user to the mail group, and the permissions > error should disappear. I'm prepared to run; $ sudo groupadd mail -g 1001 $ useradd postfix -u 1001 -g 1001 Shall I use number 1001? OR another number? However on /etc/group I found following entries; mail:x:8:dovecot dovecot:x:113: I don't have dovecot-* running. Shall I remove them manually?
