Fix DNS issue and log dumping issue on my server

Problem#1: We have one mail server which can't be access from some regions. (We are suspecting some proxy is blocking the server as it shows dmarc is not valid) Problem#2: We have three servers ended IP numbers are 98 , 114 and 101. From 98 and 114, we are dumping syslog and other logs into 101. It was working earlier. For some reason it stopped dumping log. We have a firewall server on top of those server.
