SPF alignment

SPF alignment: The envelope domain and the From domain match, or they share one organisation domain.

SPF alignment holds when the domain of the envelope sender and the domain in From are the same, or they share one organisation domain. After the return path resolves, the envelope is on a subdomain of your domain, which is what makes this true.

The SPF record on the sending name itself is recommended cover. Merge it into an existing record. A second SPF record does not add up; receivers read one.
