These records tell receiving systems which servers can send for the domain, whether the message was signed and whether the visible From address aligns with the authenticated domain.
Email Problem Diagnosis
Business email commonly lands in spam when authentication is missing or misaligned, the sending domain or server has poor reputation, recipient providers distrust the message pattern, or the mail system is configured incorrectly. The right fix depends on which signal is failing.
