I agree. Most of the ISA problems can be explained by poor DNS and/or IIS configuration. I spent some of my "holiday" chasing down DNS issues for 2 clients. In both cases it turned out that the ISP DNS was sluggish and was causing email problems for my clients. Exchange wasn't able to use the smart host with any efficiency. Messy stuff trying to explain smart hosts and DNS resolution in plain english. Maybe I should forward the article on to the ISP's! If only their staff could read. I've had to turn off NDR for two servers. I hated to do it but the queues of NDR's in Exchange were just beyond reason. You wouldn't believe the amount of junk mail that Travel Agencies and Real Estate firms receive.
