4. November 2021 - Service announcementSpam wave: Possible problems when sending emails to certain external addresses

Sending emails from university email accounts to addresses of certain external providers, i.e., United Internet (1&1, GMX, Web.de) or Yahoo, may  currently not work.

The reason: A large amount of spam was sent from a compromised university mail account, so several external providers have temporarily blocked mail reception from university email addresses (blacklisting). The cause has been remedied by the Computing Centre, but it may take some time for the providers to lift the blacklisting.

We apologize for the inconvenience!
