The problem you will find here is that because the IMS is actually an EDK gateway, the 
MTA will not re-route messages to a different IMS.  Basically, once the MTA has 
deposited the messages in the queue for the IMS, that's where they stay.

What you could consider is putting both IP addresses of your two Linux boxes into the 
one IMS.  On the connections tab, specificy both IP addresses with a comma, e.g. 
"10.1.1.1,10.1.1.2" etc.  This produces a reasonable load balancing act between the 
two Linux boxes.  Obviously, inbound messages will be load balanced if your MX records 
are set to the same preference.

Conversation: Multiple IMS in Exchange 5.5
Subject: Multiple IMS in Exchange 5.5


Exchange 5.5 SP3+ on NT4.  Right now, Exchange points to a Linux box running sendmail 
as our method of sending / receiving Internet mail.  The networking guys want to add a 
second Linux box (with it's own MX record) and a higher cost so that if the first box 
goes down mail would automatically flow to the second box.  I'm not sure how to do 
this on the Exchange side.  If I add a second IMS connector in Exchange how do I 
control which one is actively used?  The goal is to have this roll over automatically.
