my email server is working fine for sending and recieving, however even when I dont send mail I am recieving a delivery failure. Failure message is attached. Why is it giving me a delivery failure message and from what mail? seems to be from the email account to the adminispconfig@localhost
Please add: localhost.localdomain.rhwebhosting.com at the end of the file /etc/postfix/local-host-names and restart postfix. The "user" admispconfig is the ispconfig mail statistics script.
