I have ticket #CPW-48118-538, which is mail sent from an outside domain to a customer I host on JH mail servers. The answer I was given by tech support was that because this outside domain doesn’t have SPF records, we are rejecting mail. That had darn well better NOT be the case. Not everyone uses SPF, and we certainly should not be rejecting mail just because a domain doesn’t have an SPF record listed.
We have updated this ticket.Please check and provide us SMTP logs from sender side to further diagnose the problem.
