Hi guys, We are having problems with BIND, it's having a hard time resolving the name of the mail relay (public -> postfix -> relay). We are using DSN round-robin to balance the traffic. however the scheme doesn't seem to work efficiently. Have any clues on why we are experiencing this problem. Could the excessive traffic cause this error?
