It sends outbound mail on both interfaces?
It sends inbound mail on both interfaces?
I would expect that inbound and outbound use different interfaces,
therefore you can use different delivery agents.
For the default smtp transport, use -o smtp_bind_address=external-address
Use a transport map to force inbound mail to use the "relay"
transport, and that one will automagically use the right source IP
address because there is only one to choose from.
