Security Check	Result	Evaluation Detail
SPF Check What is this? Sender Policy Framework (SPF) lists the authorized sending mail servers. Lacking it allows spammers to send fraudulent emails under your domain.	-	-
DKIM Check What is this? DKIM signs outgoing mails cryptographically. Incoming servers verify this key to prove the mail source wasn't manipulated.	-	-
DMARC Check What is this? DMARC dictates action when SPF/DKIM fail (quarantine/reject). A strict setting (quarantine/reject) blocks impersonators completely.	-	-
Reverse DNS (PTR) What is this? Reverse DNS checks if the sending IP maps back to your mail host. Missing PTR records usually trigger spam classification.	-	-
