Secure Email Record For Free

While they both are authentication protocols, SPF and DKIM are not exactly the same. SPF is used to authenticate the sender and ensure that only authorized servers can send emails from your domain, while DKIM is used to verify that messages haven't been tampered with in transit.

When an email-sending organization publishes its SPF DNS record, it gives email-receiving organizations a simple tool that can flag email for potential spam, spoofing and phishing attacks.

For smooth email communication, it's essential to configure the DNS MX and A records so that other mail servers can reach your server over the Internet. There are also DNS records such as SPF, DKIM, DMARC, and TLSA for authentication, which help protect against spam and identity theft.

DNS TXT records are used for processes like email authentication because they can store important information that servers can use to confirm whether or not a domain has authorized an email sender to send messages on its behalf.

Domain-based Message Authentication, Reporting, and Conformance (DMARC) and DomainKeys Identified Mail (DKIM) are both security protocols for email. The difference between them, in a nutshell, is that DKIM attempts to verify whether mail is legitimate, and DMARC suggests what to do with mail that isn't legitimate.

Domain Name System (DNS) is the foundation of the internet that we know today. By translating host names into IP addresses, it plays a crucial role in ensuring the functionality and accessibility of emails, webpages, and other services on the internet.

1 Answer. A CNAME is just a routing rule and shouldn't affect your MX as long as they are different, i.e. the CNAME is something like blog.mywebsite.com and the MX is something like mail.mywebsite.com .

SPF uses DNS to publish the domains, subdomains and mail servers from which authorized email can be sent. DKIM uses DNS to advertise the public keys that can be used to authenticate email messages as having legitimately originated from the domain.
