IMAP and POP3 with TLS only

Screenshot der STARTTLS konfiguration im E-Mail-Client Thunderbird

With immediate effect, unencrypted connections are no longer possible. We have written to all affected persons.

During a mail server check, it was noticed that the configuration of some email clients only establish an unencrypted connection to the university's email server. The possibility of establishing this unencrypted connection was switched off by the computer center on 19.02.2024. The persons affected have been informed of this by email in the last two weeks.
Email clients must be configured with STARTTLS connection security in order to encrypt the password and content of messages during transmission.
The screenshots show this using Thunderbird as an example.
Further information on STARTTLS (and how it can be improved) can be found here.
