Dear Stan, Thanks for your reply. I notice some unknown email ids with Relay Access Denied error in maillog. It appears someone else is also trying to send email.
I have set protocol=ipv4 What should be the value of mynetworks if I want that only my server should send email. Truly appreciate your time.
