IIS6 SMTP Server problems...

iis smtp nntp: I need details on how the SMTP server does things. I had a problem where our
primary mail server was down for a service pack and another server of ours
tried to send it mail and decided to send to the backup mail server b/c the
primary was down but after it was back up, the server sending the mail kept
using the backup MX record to try to send mail for three days (even after a
flushdns and multiple restarts of the SMTP service). I noticed that this is
happening with some other domains also. This all started after these updates
were installed on all of our servers:
890175
891711
871250

Here is what I posted on another group and they evetually suggested that I
try these other groups

We got it fixed. We found an article that spoke of a bug in MS SMTP where,
for unknown reasons, the queue gets "stuck" and produces strange results.
Stopping the SMTP server, clearing the queue and restarting it is supposed to
fix the problem. It did. Everything is now fine.

I have the e-mails that caused the problem if anyone at MS is interested.
Also, I tried putting those e-mails in the SMTP queue on another computer and
it became "stuck" and produced very strange results.
