Hello all,


   Our Exchange systems forward all mail to a 'Smart Host' that resides
in our DMZ.  The Smart Host is nothing more than a Windows 2003 Server
with IIS SMTP services and GFI Mail Essentials and Mail Security.  


   As far as blocking/preventing SPAM and Virus' mail - it works GREAT.
My problem is that the SMTP service seems to flake out 2 to 3 times a
week here lately.  The SMTP service is still running and receiving mail
from Exchange, and it receives mail from the internet, but the queues
will back up and not deliver the mail at all...  A reboot of the server
will get the server to process mail again and flush out the queues...
Restarting the services does nothing to assist and there are no events
in any of the logs.


   Can anyone point me to any information that indicates what mail
volumes the standard IIS SMTP mail service can handle?   I want to
verify that we are not overwhelming the service with too much volume.
