All email addresses of a mail domain that are to be accessible from outside must be added to the central WhiteList (WL). Incoming emails are only accepted (by the MailIn server) if the addressee is on the WhiteList of TU Darmstadt and therefore is an official email address. The WhiteList prevents emails from outside the university from reaching the mail gateway and the university, which cannot be delivered past the mail gateway. Internal addresses that should not be accessible from outside the university do not have to be added to the WhiteList.
All email addresses are automatically added to the WhiteList if the server is operated by HRZ. For decentralized email servers, institutions must independently add email addresses to the WhiteList.
- Shipment must be encrypted.
Entry in the WhiteList
The registration for MailIn in the WhiteList takes place via web form:
Application for entry of an e-mail domain in the WhiteList (in German)
Important: If an entry for the WhiteList no longer has a valid TU-ID from the administrator, this entry will be removed within a short period of time. Similarly, email domains that do not have valid entries in the central DNS will be removed as well.
