From June 2026, we will be making important changes to the TUBAF mail system. You must take action if you send mails with your TUBAF address via an external service provider such as GMX or Gmail. This also includes sending newsletters and confirmation emails.

The introduction of the new security system (DMARC) prevents attackers from using email addresses of TUBAF members on the internet.
In future, emails with a personal TUBAF sender address, such as name.firstname@[department].tu-freiberg.de, can only be sent via the TUBAF email system.
If you currently use external service providers with a TUBAF email address (e.g. for newsletters), please contact our IT Service Desk.

The roll-out of DMARC starts in June and will take several months. We will keep you informed about the progress on this page. If you have any questions, please contact the IT Service Desk.
