infusionmail.com is authorized to send on behalf of my domain, however, it looks like SPF is still failing DMARC’s alignment test. DMARC looks at the Return-Path of a message to make sure the domain there matches the domain in your From address. If the Return-Path path doesn’t match the From address, those messages will fail DMARC’s SPF alignment test.
Anyone had this issue? IS standard reply is that it is my problem but after 30 minutes of re-education they understand the problem and have informed me that the return path cannot be adjusted. This is not being prioritised as an issue because chat support is giving misguided advice i.e. “go speak with your provider”. All of the online tests for DMARC and SPF for my domain have passed but it looks like some do not test for the return path. It is very confusing but I would like to eliminate it as a possible cause of email rejection.
