Increased email security with DKIM

2025/01/28

From 05.02.2025, the DKIM authentication procedure will be activated for all subdomains *.tu-darmstadt.de in the central groupware service.

To improve email security, the DKIM authentication procedure will be extended to about 240 subdomains that are managed by the central groupware service (Exchange) provided by the HRZ. Further domains will follow shortly.

We already informed you about the background in our HRZ News in December 2024.
