I have two domains. forest domain abc which has the exchange infrastructure. forest domain xyz which does not have exchange. There is a two way trust set up.
I have set up database mail which sends internally but not externally on the xyz domain its uses mailrelay address to comunicate with exchange. The receive connector is set up correctly on exchange on domain abc as I have managed to send email from a sql server to external contact in the abc domain.
The IP addresses are correct on the receive connector.
The problem is I am unable to send to an external contact from the sql server in the xyz domain. Not sure if this an exchange issue or database mail.
Any advice would be helpful.
