emailverifier's Introduction

Verificador de E-mails

Ferramenta para a verificação de domínios de e-mail.

Como é o processo? São avaliados três elementos:

  1. MX Record (Mail Exchange) - Um registro DNS que especifica os servidores de e-mail autorizados a receberem e-mails para este domínio.

  2. SPF Record (Sender Policy Framework) - Mecanismo de segurança que lista os servidores autorizados a enviar mensagens usando o nome deste domínio.

  3. DMARC Record (Domain-based Message Authentication Reporting and Conformance) - Elemento que informa os servidores quando uma mensagem não é autenticada, para que tomem a ação apropriada.

Domínios sem estes elementos possuem graves falhas de segurança.
