Email Relay from outside server
I have an Exchange server running emails for a sister company that I created and open relay for in the past and has worked perfectly fine. Until I added a new ISP at the site of the exchange server. All of our host records have been updated. My problem now is that I can receive inter-company emails relayed from the outside server, but I get a failure on sending outside emails form that server.
all other emails handled locally at the exchange server site work perfectly fine.
Any ideas why internal emails will relay but not external just from changing the ISP? Our old ISP is still connected for failover.

My MX records are correct. Emails for my other 2 domains are working perfectly. What could cause emails from this relay to work for internal domains but fail when sending to external domains?

Also, I shouldn't say that that the ISP has fail-over in DNS because GODADDY cannot handle that. But it is setup on my Sonicwall Firewall.

Issue was due to my own changes on our firewall. It happens.
