I purchased a new domain. Setup MX records to point to our exchange server. Everything seems to be setup correctly and started receiving emails. Now we get an error stating:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 <***@currentlightingelectric.com>... Relaying denied (state 14).
Not sure what else to do.
