I am running QuickDNS pro 2.1.1 and have checked it with the DNS Expert. The checked result is saying that my mail server is prone to relay mail and may be attacked/spamed by someone else. I cantacted the Vendor of those DNS products and they think there should be something with the mail server itself to prevent spaming. I am wondering if there is some special setting to do this. I keep receiving unrelated mails from the internet. How can I solve this problem? Please kindly help me.
