La Poste, one of France’s largest email service providers, has announced a major update introducing new email authentication requirements to better protect its users from phishing and spoofing.

Starting in September 2025, every email sent to a @laposte.net address must pass three critical authentication checks: SPF, DKIM, and DMARC. If your emails don’t meet these standards, they’ll be flagged as spam or blocked entirely.

This announcement is more than just a local policy update. It brings Europe in line with global providers, setting a new standard for trust in digital communication.

What the Enforcement Means

La Poste will require senders to:

• Authorize servers with SPF records
• Sign messages with DKIM to confirm authenticity
• Apply DMARC policies to dictate how failed messages should be handled

For businesses, compliance has now become mandatory. If these standards are not configured correctly, customer messages could go unseen.

Why Enterprises Cannot Afford Delays

Unlike gradual rollouts, La Poste’s policy will affect all senders simultaneously. This creates immediate pressure for:

• Banks and financial services sending time-sensitive alerts
• Retailers and service providers that depend on La Poste customers
• Public institutions communicating with residents throughout France

A mistake in authentication could hurt not just message delivery but also trust, brand integrity, and compliance.

The Global Context

The timing is intentional. Cybercrime damages are expected to exceed $10 trillion by end of 2025, with phishing being a major factor. By enforcing strict authentication, La Poste is joining a global effort to reduce spoofing, protect users, and build a safer digital environment.

Common Pitfalls to Avoid

• Incomplete SPF records that do not cover all legitimate sending services
• Misconfigured DKIM keys that disrupt alignment with domains
• Overlooked DMARC reports that could have revealed abuse before it caused damage

Without regular monitoring, organizations risk losing sight of how their domains are being used or misused.

How Organizations Can Get Ahead

As authentication rules become stricter, enterprises need more than quick fixes. Skysnag makes email compliance easier by:

• Automating SPF, DKIM, and DMARC deployment across domains
• Offering real-time visibility into authentication reports to quickly spot abuse
• Blocking spoofing attempts before they harm brand reputation

With automation, businesses can spend less time fixing DNS records and more time on their main operations.

Preparing for the Future

La Poste’s new enforcement should be seen as an opportunity, not a burden. By adopting authentication, organizations can:

• Ensure essential communications are delivered
• Protect brand trust against impersonation
• Enhance compliance in regulated industries

Become Compliant Before the Deadline

With La Poste setting a September 2025 deadline, the time to act is now. Whether you’re sending a simple business message, transactional notification, or a full-scale marketing campaign, your emails must be properly authenticated to ensure they reach your recipients’ inbox.
