This is a neat tool to test for open relays. Whilst most true open relays are not out there these days, internal relay is as dangerous? Why? Imagine Mr Tom Smith is the boss of Mr Jack Miller. Now Jack Miller sends an insulting email to Tom Smith which could terminate his work contract. Likewise a fake Smith to Miller mail could create serious disturbance. We come across those internal relay problems in many of our audits. Disable internal mail relaying!
