I am getting this error message in my Production environment. This is coming during the User creation and as the user is created a mail goes to the user with the Password and other details
Net::SMTPFatalError occurred in users#create:
550 Relaying denied
Any Idea on this?
This worked for me:
The servers MIP (Mapped IP) address needs to be added to the mail router’s relay list. It was not added and that was the reason it was rejecting. The receiver IP address was added and the mail was sent again.
