Amy:
That sounds like my experience when I configured GFI MailEssentials to
"generate NDR" on my Bayesian filter.
The network slowed to a craw, and Exchange stopped working whilst
handling 1,200,553,023,832,001 messages in the Q.
And, everyone was pointing to the newly installed ISA2004. Had it not be
for the fact that local email exchanges being delayed, it would have
been a much longer day for me.

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.
