About this event

Practical guide to implementing and enforcing SPF, DKIM and DMARC so your domain cannot be easily spoofed. Covers how the three records work together, a safe path from p=none to p=reject, handling third-party senders with subdomains, and the next steps beyond DMARC.

Mailbox providers have moved from recommending email authentication to requiring it.

This session shows a practical path from a monitoring-only DMARC policy (p=none) to full enforcement (p=reject) without losing legitimate mail. You learn how SPF, DKIM and DMARC work together — with a clear focus on alignment — and how to identify and fix every legitimate sender that uses your domain. We also cover why dedicated subdomains make enforcement much easier, how to lock down parked domains, and the next layer of protection with MTA-STS, TLS-RPT and BIMI. You leave with a step-by-step enforcement plan and a checklist you can apply immediately.
