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  and place it in front of 
your corporate Exchange Servers .  Barracuda Networks, Symantec and MacAfee 
also make an excellent SMTP Smarthost or Mail Relay ( In the Unix world they 
call it a SMTP Proxy ) with Anti-Spam and Anti-Virus capabilities built in. As 
much as I like Exchange, I have concerns regarding possible breaches in 
security using it as a SMTP front end in a large corporate or government 
enviroment. There are lot's of worms written specfically to take down an 
Exchange Server and it's nice to stop them before the actually hit an Exchange 

Just a thought, 

Jose Medeiros

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.
