Hardly. There are a lot of exploits for older versions of various mail servers that allow attackers to get around the restrictions. ordb.org, as someone else mentioned, is a good place to start as is (IIRC) abuse.net. You don't want to run one simple test, you want to run tests that check for all or most of the exploits out there. -- Steve Sobol/CTO/JustThe.net LLC/Mentor On The Lake (Cleveland), OH/888.480.4NET "This country has a strong ethical foundation, but...
