I have some people in our company not able to receive outside email. We changed websites last week so that might have something to do with it but it has not affected everyone. This is the message I get back from email I attempted to send.
Technical details of permanent failure:
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 recipient <firstname.lastname@example.org> unknown #292 (k98A4A228980290900) (state 14).
Any help would be appreciated
