I have a mail-enabled security group with users and contacts included. When I send an email to them from internally, all members get the email without issue; however, when they respond or reply to the email, they are receiving an undeliverable error "not authorized to relay messages". The setting for delivery mgmt has "senders inside and outside of my organization" is checked. Any thoughts? Thank you.

Which server is generating that message? What does a message trace show?

Post the full NDR message or the message trace details
