In order to improve the protection of the central mail gateway and thus make an important contribution to the increased security level in the science network, the HRZ is required to ensure SPAM and virus protection via the German Research Network (DFN).
This means that all incoming and outgoing e-mails must be routed via the DFN portal in future.
Administrators of decentralised e-mail servers must register e-mail domains that have not yet been converted.
Please also bear in mind that the target e-mail address must be entered on a so-called whitelist (database of legitimate domains).
Firewall changeover as of 15 September 2023
From 15 September, the HRZ will change the firewall in such a way that then only e-mails will be forwarded externally or to the DFN mail protection.
