i know this subject was discussed at length yesterday but I'm having a different problem that the one hungster was talking about.
i followed a few different sets of instructions on blocking external relay, however, each time i did it i blocked all mail being sent externally. Internally addressed mail worked but nothing else.
i tried two different things to filter.
1. in routing restrictions i set it to only do open relay for authenticated users
2. in routing restrictions i set it to only allow internal ip address range.
192.168.0.1 / 255.255.255.0
anyone have any ideas to what i'm doing wrong. i'm running exchange 5.5 in case that makes a difference.
