Service announcementOutgoing mail server mail.urz.uni-heidelberg.de: Sending mails from end devices outside of Germany only possible via VPN

For security reasons, sending emails via the university's outgoing mail server mail.urz.uni-heidelberg.de is currently only possible from end devices within Germany (in the area of the top-level domain "DE") or with a VPN connection to Germany (e.g. to the university VPN server).

  • This applies to sending emails from applications such as Outlook or Thunderbird.
  • Emails can still be sent without restriction via the webmail interface SOGo.
  • Exchange email accounts are not affected by this measure.

We apologize for the inconvenience!
