Just on the topic of Digest emails, I got this bounce today. Is it because of the From: and To: fields or a more fundamental problem? Action: failed Status: 4.0.0 Remote-MTA: dns; eu-smtp-inbound-1.mimecast.com Diagnostic-Code: smtp; 451 Open relay not allowed - https://community.mimecast.com/docs/DOC-1369#451 From: listname-requ...@example.co.uk Subject: Listname Digest, Vol no, Issue 1 To: listn...@example.co.uk Reply-To: listn...@example.co.uk The Mimecast website states: "Both the sender AND recipient domains specified in the transmission are external to Mimecast, and aren't allowed to relay through the Mimecast service and / or the connecting IP address isn't recognized as authorized. Mimecast customers should contact Mimecast Support for add the Authorized Outbound address, or to take other remedial action."
