New DMARC Policies – What’s Changing and Who
Simple and very practical. A DMARC record is quickly set up and immediately helps to combat spam and phishing.
Have you already heard about the DMARC obligation from February 1, 2024 and are wondering if and what you need to change in your mail domain?
Don’t panic!. Here you will find answers to these questions:
What is DMARC?
DMARC gives domain owners more control over the authentication of their emails and helps reduce fraudulent practices. It is used as a supplement to the well-known SPF system and is stored in the DNS of the sender domain in the form of an additional TXT record.
For a detailed explanation of DMARC and how to use it, check out this FAQ article.
What is changing?
DMARC is an invention of Google, Yahoo, and Microsoft to prevent address forgery. DMARC is intended to complement the established SPF system. Since November 2022, Gmail has been the only known mail provider to no longer accept mails whose sender domain cannot be validated by SPF or DKIM. Both Gmail and Yahoo are expanding these requirements earlier this year:
From February 1, 2024 , a DMARC obligation will also apply to all sender domains that send more than 5000 emails to Gmail or Yahoo addresses per day.
What do I need to change?
Initially, there is only an obligation for companies that work with massive mass mailings, where at least 5000 mails are actually sent to Gmail addresses only every day. That’s a lot of e-mails, for which external services usually have to be used to send mass newsletters. If you use the SecuMail Relay for outgoing mail and do not use external service providers for mass mail, you should not have to make any changes at this time.
What happens next?
Since the limit of 5000 emails per day seems rather arbitrary, it should be expected that this will only be the first step in the nationwide introduction of DMARC. A DMARC record is quick to set up and helps malware control systems immensely against address spoofing.
Therefore, we recommend entering a DMARC record in general and regardless of the Gmail compulsion. Feel free to use our DMARC suggestion from the FAQ or contact us at:
