This is my first time in posting anything and i hope i wont say smtg wrong or stupid....if so, please forgive my ignorance.....

I am an Administrator in a Group of Exchange servers .... I have found them ready from the people i replaced and i care about their security..... i have found everything for the firewalls and the DMZ and all the rest..... but i wonder if you know any sites about Exchange security problems ......

Thank you in Advance
