Any in your example server123.example.net is also an email domain, right?

So domain D1, D2 map to ip IP1. When checking in the context of D1 it will
check whether IP1 maps to D1 and the check will succeed. In the context of
D2 similarly it will succeed. It won't get paranoid about IP1 having 2
domains. Then it sounds good.
