Emails with DMARC, DKIM and SPF
The three main email security protocols DMARC, DKIM and SPF, which complement one another, are implemented by us for a secure hosting. All three together provide the best protection.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a technology to extend the capabilities of the SPF and DKIM sender policies. The DMARC policy defines how the receiver should treat email messages depending on the results of DKIM and SPF checking. This technology is based on the rules specified in the sender’s DNS zone.
DKIM (DomainKeys Identified Mail) provides a method used to validate a domain name identity that is associated with a message. It lets an organization to take responsibility for a sent message by attaching an automatically generated digital signature to it and uses cryptographic techniques to validate authorization for the signature presence.
SPF (Sender Policy Framework) is a method used to prevent sender address forgery, i.e. using fake sender addresses. SPF allows a domain’s administrator to set a policy that authorizes particular hosts to send mail from the domain. A receiving mail server checks that the incoming mail from a domain comes from a host authorized by that domain’s administrator. SPF is based on the rules specified by the administrator in the sender’s DNS zone.
