Secondery Send Connector on Exchange 2007 doesnt work

Hi ,

We have Exchange 2007 with on windows server 2008 r2 on our first site with an mail relay (Third party ) and on our second site we only have an additional mail relay for redudncy purposes

Our goal is that the send connector will be fault tolerance only and not "Round Robin" so only in case of a failure in the first send connector it will send to the second. so when i found the following article i was thrilled that there is a simple solution to create a second connector  (MJLongman answer)

so i created them with the following configuration

which you can see that the first one (MAIL SMTP) works with the cost of 1 timeout of 01 min and the ip that ends with .3
and second connector that i created (Remote Mail) with Cost of 5 timeout of 10:00 min (default) and the ip that ends with .33

the problem that as soon as i shutdown the first mail relay (for testing purposes) that IP ends with .3 it should have started working with the second send connector which ends with .33 after a minute but instead it just queued on the first send connector and didnt even see the second send connector in the queue viewer ( i tried reseting the services and even the exchange server itself but it still didnt work) it still didnt add 4th hop for the second send connector

please note that if i added ip .33 at the first send connector as an additional smart host everything worked as round robin so there are no problems in the second mail relay ...

any idea how can i configure it as fault tolearnce that only when the first smart host (.3 ) fails it will try to send to (.33) ?

    Still you can add multiple smarthost into the same send connector. it will work as a fault tolerance.

    When you add a smart host it works a round robin meaning both of then and fault tolerance I want to be only fault tolerance not both..

    Any solution for that needs a second connector that works with cost
