DMARC is an e-mail authentication policy that tells receiving servers what to do with messages that claim to come from your domain but fail SPF or DKIM checks. You can ask them to monitor, quarantine or reject such mail, and receive reports about who is sending in your name. For a business this is the main defence against spoofed invoices and phishing e-mails that misuse its brand. A careful rollout starts with monitoring, fixes every legitimate sending service and only then tightens the policy. Internet Solutions administers mail servers and hosts business e-mail on its own infrastructure, so DNS records, authentication and spam protection are handled together. Correct DMARC also helps newsletters and transactional e-mails reach the inbox. Reports from receiving servers also reveal forgotten services that send mail in your name.
