You’ve probably noticed that fraudsters spoof email addresses in their phishing attacks and other scams. They are probably spoofing your company’s email addresses too, sending messages to your customers and employees. While spoofed email using your domain name can’t be eliminated entirely, it can be reduced and/or marked as spam. You can also increase the likelihood of your legitimate emails being delivered to inboxes instead of spam folders. MacMaven Consulting can configure the following three technologies for your company.
SPF (Sender Policy Framework): This DNS entry lists the servers that are authorized to send email for your domain.
DKIM (DomainKeys Identified Mail): This mechanism digitally signs your messages. Your domain’s public key is published in DNS.
DMARC (Domain-based Message Authentication, Reporting and Conformance): This mechanism ties SPF and DKIM into a policy published in DNS. It is also used for reports that give you feedback about delivery successes and failures.
