The three core email authentication standards - SPF ([RFC 7208](https://datatracker.ietf.org/doc/html/rfc7208)), DKIM ([RFC 6376](https://datatracker.ietf.org/doc/html/rfc6376)), and DMARC ([RFC 7489](https://datatracker.ietf.org/doc/html/rfc7489)) - work together to verify that an email genuinely originates from the domain it claims to represent.
> The email authentication landscape changed permanently in 2024, says Brad Slavin, General Manager of DuoCircle. Google, Yahoo, and now Microsoft all require DMARC. What used to be a best practice is now a hard prerequisite for reaching inboxes. Organizations that delayed are now paying the price in deliverability.

La Poste is one of the biggest email services in France. Millions of people use Laposte.net for their personal email. **Starting from September 2025**, they are making a big change. Now, every email sent to Laposte.net addresses must pass three important security tests: [SPF](https://autospf.com/blog/spf-guide-understanding-sender-policy-framework/), DKIM, and DMARC. If your email doesn’t pass all of them, it will go straight to the spam folder. No exceptions.
It doesn’t matter if you are sending a simple business email, a [transactional message](https://docs.mapp.com/docs/transactional-messages) from your app, or a [marketing campaign](https://www.geeksforgeeks.org/marketing/marketing-campaign-us/). If your setup isn’t correct, your email will not reach the inbox.
This change is not only happening in France. Other countries and big \*\*email services are doing the same thing. The goal is clear: stop fake and dangerous emails from reaching people. [Spoofing and phishing](https://www.msspalert.com/brief/novel-usps-spoofing-phishing-attack-relies-on-malicious-pdfs) attacks are becoming smarter and more common. So, companies need to keep up or risk losing trust and customers.
## Why Laposte.net’s new rules matter for everyone?
Email security is no longer something you can ignore. It is now a must-have. Rules like [GDPR](https://www.investopedia.com/terms/g/general-data-protection-regulation-gdpr.asp) in Europe and [CCPA ](https://en.wikipedia.org/wiki/California%5FConsumer%5FPrivacy%5FAct)in the US have always been about **protecting personal data**. But now, they are pushing companies to secure email too.
Most fake emails occur because companies fail to set up their security properly or neglect to update their settings. This makes it easy for hackers to impersonate someone else and [steal data](https://www.bbc.com/news/articles/cd6nyng861wo) or [spread malware](https://gbhackers.com/socgholish-uses-parrot-and-keitaro-tds/). That’s why governments are implementing stricter rules to compel companies to address these issues.
Laposte.net’s new rule is a perfect example of this **global trend**. It’s a way to make sure companies don’t leave their email systems open for attackers.
## Big email services are already doing it
_When big players like La Poste tighten their rules, other companies follow soon after. Microsoft makes sure emails meet DMARC rules for Outlook._ Gmail blocks many fake emails with strong filters. Yahoo also punishes senders who don’t use proper security. This is not by chance. It happens because [fake emails](https://tradebrains.in/fake-email-scam-nigerian-fraudster-tricks-trump-donor-steals-250000/) are growing in number and complexity every day.
Businesses ignoring these changes are playing with fire. Just as laws about \*\*data protection have forced companies to rethink how they store personal information, these email rules force companies to rethink how they send and **protect emails**.
## Smart companies are preparing for the future
Good companies don’t just care if their emails reach inboxes. They want to build trust and **protect their reputation**. People don’t just want their emails to work; they want to be sure their communication is safe and coming from real sources.
New solutions, such as [BIMI](https://dmarcreport.com/blog/the-role-of-bimi-in-the-fight-against-email-fraud-and-scam/) (Brand Indicators for Message Identification), are also gaining popularity. These help show a company’s logo next to the email in the inbox, but they only work if the right security measures are in place.
## Simple steps to follow Laposte.net’s new rules
It is not just about turning on SPF, DKIM, and [DMARC](https://dmarcreport.com/what-is-dmarc/). You need to set them up the right way. Here are some smart practices to stay safe:
## 1\. Keep track of who sends emails for you
Many companies forget to track all the places their emails come from. _Even subdomains like marketing.yourcompany.com or support.yourcompany.com can be used by attackers if not managed properly_. Using tools that scan and list all your sending sources can help you spot problems before they happen.
## 2\. Fix SPF limit issues
SPF works great, but it has a minor issue. There is a limit of 10 lookups allowed. If you use too many [third-party services](https://www.websitepolicies.com/blog/third-party-service-provider) for sending emails, SPF may fail to function properly. A solution called \*\*SPF flattening helps by listing IP addresses directly instead of using too many includes. But this needs to be updated regularly to stay accurate.
_Also, make sure your sending IP is linked to your domain. Otherwise, hackers could exploit the gap and send fake emails pretending to be you_.
## 3\. Change DKIM keys regularly
[DKIM](https://dmarcreport.com/what-is-dkim/) makes sure no one changes your email while it travels. But if a \*\*DKIM key is stolen, the thief can send fake emails. That is why it’s important to rotate keys often. Big companies add new keys in DNS first, check everything works, and remove the old keys after confirming.
## 4\. Take DMARC enforcement slowly
_Jumping straight to blocking all unauthenticated emails (p=reject) is a risky approach. You could accidentally block your own emails._ Instead, follow this step-by-step method:
- Start with p=none: Monitor who is sending emails and spot issues.
- Move to p=quarantine: Flag suspicious [emails as spam](https://cybernews.com/news/microsofts-breach-notification-emails-end-up-in-spam-folder/), but still keep an eye on reports.
- Finally, set p=reject: Block all unauthenticated emails once you are sure everything is correct.
Always check your [DMARC reports](https://dmarcreport.com/blog/how-to-read-dmarc-reports-guide-2026/). They help you \*\*fix minor problems before they become big disasters.
## Don’t wait until it’s too late
Setting up proper [email security](https://dmarcreport.com/blog/why-email-security-matters-and-how-to-get-it-right/) is not easy. Doing it yourself can be confusing and risky. That is why working with experts like [DMARCReport](https://dmarcreport.com/) is smart. We \*\*provide tools and support to help you set up and manage SPF, DKIM, and DMARC in the right way.
The best time to act is today. Don’t wait for the deadline. Get your \*\*email system ready, keep it safe, and make sure your messages always reach people’s inboxes.
