I have a home lab setup for learning exchange 2013.
I have setup two email domains dm_test_a.co.uk and dm_test_b.co.uk I have a number of test users setup on each email domain and able to send internal email to each. all seems okay.
I have two internet connections and each have a smart relay of their own and I want dm_test_a.co.uk to relay via isp1 and dm_test_b.co.uk to relay via isp2.
using the send connector I have setup each of the isp's smart relay and each is working when the other is disabled so I am confident that the send connector is correct. however I cannot work out how I assign a send connector to a particular source email domain.
thanks.
