Source: Own illustration
In this post of our email security series, we would like to inform you about an upcoming tightening of the SPF policy that will apply to RWTH Aachen University as of December 5, 2024. The change will prevent RWTH email addresses from being used as sender addresses by mail servers outside of RWTH Aachen University in the future. This will further increase email security at our university. Please note that this article is mainly intended for mail administrators of RWTH institutions. (*)

In the fourth part of our e-mail security series, we would like to inform you about an innovation in our e-mail security policy.
After we reported on e-mail, e-mail statistics at RWTH Aachen University, and the SMTP protocol and its pitfalls in the first and second articles, and informed you about the DKIM identification protocol and DMARC in the third article, this fourth part is now about a new e-mail security requirement. To ensure that RWTH can continue to provide a secure e-mail service in the future, we have decided to introduce the evaluation of a sender’s DMARC policy when accepting mail at the university’s central mail gateway. You can find out what this means in this blog post.

Even today, the exchange of messages via e-mail is undoubtedly an important way of exchanging information between parties via an asynchronous communication channel.
