Independantly exchage is working fine but when i configure it behind ISA it wont send mail outside. although i will recieve mails properly from outside. When I try nslookup it will resolve hotmail.com but first i have to resolve my dns as nslookup dns.ISPEngineering.homeip.net then my mail server as nslookup mail.ispengineering.homeip.net and then nslookup hotmail.com It resolve hotmail but if try to resolve after resolving dns it want resolve and dns resolution is timed out. I configure my ISP's dns as a farwarder for my dns. and i also configure Server publishing rules plus protocol rules plus site and content rules for dns and mail ie open port 53 and 25(SMTP). In exchage I configure it to use external DNS and i try both (one by one) to farward my mail through dns or to a smart host but it wont work. Please Kindly help me my last date of submission is 15th of this month and I also have to complete documentation.
