Winows 2000, SP4, IIS5.0, Norton AVCE 7.6, Brightmail 5.5 AntiSpam.
Messages build up in queue directory, delivery becomes slow and eventually
delivery to one of my domains stops altogehter. I have 45 Domains configured
under the Virtual Server. All Domains are configured to forward mail to
Smart Host by [IP address]. NAVCE 7.6 has exclusions for Inetpub\mailroot
and all sub-directories. Question: Why does mail build up in queue and nver
expire and why does delivery to ONE domain seem to fail after a period of
time? So far the only way I know to fix this is to recycle SMTP several
times until queued mail is delivered. After a couple of weeks the same thing
happens all over again. Any Suggestions? Microsoft's classic response is to
uninstall 3rd party apps. Well, If I uninstall 3rd party apps I have no use
for the MS SMTP relay!!

Neil,

Looks like a DNS problem with the domain that keeps getting queued. Go
to http://aboutmydns.com and run the quick test against that domain
