We plan to change mailserver. But until all users is moved to the new server I cannot change the domain Destination Routing for our mail domain.
I have tested adding two destination hosts, if delivery fail on the first the second is used.
This did not work. I receive a Invalid recipient address error from the first host. The second is not used at all.
Can I use Directory data source to make a Routing Query?
It look like it working but when run a test mail, the mail is not delivered.
I have used the field Alternate mailhost attribute to point to the correct mailserver. I used the carLicense AD attribute.
But how can I always use that field?
