Dear All Now I am able to send receive mail from my domain. Now I wanted to create new email accounts using below command.
useradd -s /sbin/nologin username passwd username User is added to machine. Next I tried to login to that account from my mail client, it fails. When I checked /var/mail folder I do not see any new account mail file there. Previously I had created one account, and I see corresponding mail file is present in /var/mail path My question is what is the correct way of adding a new mail account in postfix/dovecot based email systems. The mail file should be of what permission. Many thanks Austin
