Hi,
Since yesterday I've had 8 messages undelivered to me getting bounce backs as "Undelivered Mail Returned to Sender"
Each has had "Temporary SMC Policy Violation detected...(in reply to end of DATA command)"
I use a catchall address for anythingIwant@mydomain.com and everything gets delivered to my virgin email address. This system has been in place since ntlworld days and nothing has changed on my end. The messages seem to pass dkim, spf and dmarc and are from a variety of individuals and companies so there is no consistency as to which ones get bounced.
Any help in making sure that I receive all of my emails would be appreciated
