Email

Oxy

DMARC policy not found

DMARC policy was not found. This makes it easier for attackers to send email from this domain. A DMARC policy should be deployed for this domain.

SPF policy uses ~all

This record should preferably not use the ~all mechanism, as this does not instruct the mail receiver to reject messages from unauthorised sources. When DMARC is not being enforced, -all should be used on the SPF record.

SPF enabled

Sender Policy Framework (SPF) records prevent spammers from sending messages with forged addresses.

SPF syntax correct
