Verificador de registro SPF

Para implementar o SPF (Sender Policy Framework), você precisará ter um registro SPF válido. O verificador de registro SPF fornece um verificador de registro SPF para validar seu registro SPF.

What is SPF?

  • SPF (Sender Policy Framework) is an email-authentication technique used to prevent spammers from sending messages on behalf of your domain.
  • With SPF, an organization can publish authorized mail servers.
  • Together with DMARC, SPF helps the receiver (or receiving systems) determine how trustworthy the origin of an email is.

How does SPF work?

  • SPF, like DMARC, is an email authentication technique that uses DNS (Domain Name Service).
  • It allows you, as an email sender, to specify which email servers are permitted to send emails on behalf of your domain.
