The maintenance for the TU Wien Secure E-Mail Gateway, see https://colab.tuwien.ac.at/x/vAJ1C, opens an external URL in a new window requires another appointment to complete the process. There were no interruptions during the maintenance window that has already taken place.

On Friday, September 27, 2024 there will be another maintenance window from 3:00 p.m. to 6:00 p.m., where there will be a delay in incoming and outgoing emails from the upTUdate environment. The emails will be accepted and saved, but will not be sent until after the maintenance. The encryption/decryption/signing should be preserved.

Those without an active secure gateway encryption option are also affected, i.e. essentially all mail domains that are hosted on upTUdate (typically on mail.intern.tuwien.ac.at).
However, direct upTUdate-to-upTUdate communication is not affected.
