spammers and spoofers

Protect your email by adding DKIM, SPF and dmarc records to protect your email accounts from spoofing and spam. These records help prevent email spoofing by setting a policy for mail sent from unauthorized mail servers. This should help prevent spoofing and bounce-backs going forward.
