Hi Chris,
This may not be the answer your looking for, however if I were you, I would
replace that Exchange Smarthost with a Mirapoint Razorgate in front of your
corparate Exchange severs http://www.mirapoint.com/products/razorgate.shtml ,
Barracuda Networks box, Symantec and MacAfee also an excellent SMTP Smarthost (
In the Unix world they call it a SMTP Proxy ) with Anti-Spam and Anti-Virus
capabilities. Ax much as I like Exchange, I have concerns regarding possible
breaches in secuity using it as a SMTP front end in a large corporate or
government enviroment. There are a lot of worms written specfically to take
down an Exchange server and it's nice to stop them before the actually hit an
Exchange box.
Just a thought,

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.
Regards,
Chris
