Virtual mail domain

The following text is about e-mail addresses that look like this one:

Such addresses normally require that the institution which is named at the end of the address runs its own mail server. Otherwise users have to settle with an e-mail address like As the above mentioned address is very popular with a lot of users in order to express an affiliation with a certain institution, the RRZK established a so-called virtual e-mail domain. This way we can create a certain e-mail address, the only condition would be that you have an employee account.

Note: The administrative effort for establishing such a domain is high. That is the reason why this is primarily thought to be an substitute option for employees who used to have an e-mail address provided by a mail server of their institution. Such a domain will not be established as a contact address. If you would like to have a contact address, please use this application form.

Establishing an employee account.

Applying for a virtual domain

Heads and administrators of university institutions can apply for a virtual mail domain with an informal letter or e-mail. The application (to the RRZK, attn: Herrn Hagedorn or via e-mail to Postmaster) should contain:

  • The requested domain name
    (above mentioned as "institution", for example "rechenzentrum"),
    capitalization carries no weight, hyphens are possible.
  • An administrator who needs to own an employee account (please tell us the name of the employee account as well as the e-mail address and phone number).

Now that the RRZK established a mail domain for the institution, employees can apply for an e-mail alias in the virtual domain. Please use the online form for the application. This way we can generate an additional e-mail address (as it is common for alias addresses). The already existing addresses and possibly continue to exist.
