RE: How I spent my Christmas vacation

Hi Amy,
 
You bet! The DNS stuff can drive you crazy. That's one nice thing about
the Exchange SMTP service, that you can disable NDRs. You can't do that
with the IIS SMTP service. I'm hoping that the Longhorn IIS SMTP service
will allow for the same functionality.

        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.

things turn sluggish!
