Email remains the backbone of corporate communication. However, without strict authentication records, legitimate business emails frequently end up in spam folders or fall victim to domain spoofing.
1. The Holy Trinity of Email Authentication
- SPF (Sender Policy Framework): Specifies which server IP addresses are authorized to send email on behalf of your domain.
- DKIM (DomainKeys Identified Mail): Adds a cryptographic signature to outgoing messages to prove authenticity.
- DMARC (Domain-based Message Authentication): Dictates how receivers handle emails that fail SPF/DKIM validation (none, quarantine, or reject).
