Exchange 2010 - Send Connector High Availability

Question

Hi All,
I performed a successful migration a few years back from a single node Exchange 2003 server to a two node Exchange 2010 organisation with a DAG and Kemp load balanced CAS array.  The solution works well and when we simulate a site failure
I am able to get the second node to handle all mail functions.
The one problem I have though is that I have to manually disable the send connector on the primary server in order for the one on the secondary server to be in use.  I should explain that I have two send connectors as I do not want the secondary server
to be used unless the primary server is down or the route is unavailable.  I realise that Exchange 2010 does not know whether the SMTP route is down or not so will just continue trying to use the send connector from the primary server (until I tell it
not to by disabling it).
My question is how do I get this to happen automatically?  Does anyone else have an example of how this could be done or use a PowerShell script to achieve this?  I guess a script could check the route and disable the send connector on the primary
server if necessary, but how would one do this?
Any help greatly appreciated.

Hi,
According to your description, your secondary send connector cannot be automatically used when the first one is down. If I misunderstand your meaning, please feel free to let me know.
If yes, I’d like to confirm if the settings of the secondary one is same with the first one and we can check the connectivity logs including diagnostic information for Healthy Server Selector.
For more information, you can refer to the following article:
