The hosting is equipped with mail authentication technologies: SPF, DKIM and DMARC. These technologies protect your mail against impersonation by cybercriminals. SPF (Sender Policy Framework) defines from which servers mail from a given domain can be sent. This record works within the DNS service, which is responsible for the correct identification of the mail server. It allows correct verification of the message at the recipient of the message. DKIM (DomainKeys Identified Mail) is used to confirm that it was you who sent the email and not someone impersonating you. The recipient’s server, when receiving a message, communicates with the DNS records of the sender’s domain and checks the signature. This makes it virtually impossible for an unauthorized person to impersonate the sender. DMARC (Domain-based Message Authentication, Reporting & Conformance) is an initiative that companies like Google, Facebook, PayPal, and Amazon are working on and using. DMARC combines both SPF and DKIM and offers additional security features.
