DMARC alignment

DMARC alignment: A pass when either DKIM alignment or SPF alignment passes for the From domain.

DMARC asks a receiver to check DKIM alignment and SPF alignment, and it passes when either one passes. The TXT at _dmarc on your sending domain is recommended. A domain verifies and sends without it.

Start the policy at p=none with a reporting address, read the reports, then tighten the policy. The record does not block verification.
