Dear All,
I have configure postfix mailserver. In mynetwork parameter i have declare my ip address like that

mynetworks = 127.0.0.0/8, 180.149.0.0/19, 58.97.128.0/17, 180.149.9.76

But when i am sending mail using ip 180.149.9.76 postfix mail.log shows error that

debian postfix/smtpd[612]: disconnect from unknown[180.149.9.76]

why this error come as i have declare this ip in my network.
can anyone help me??

Declaring this IP in "your network" co-ordinates with the permit mynetworks directive to allow sending of mail. The resolution of the IP address is handled by DNS, which apparently this IP address does not have proper reverse resolution. When I try to perform a lookup on it, I receive a non-existent domain error. You must be too, which is why you are getting "unknown".
