Mailing lists at ZIM

For institutes, working groups, student and other groups within the university, ZIM sets up mailing lists as needed. Instead of managing a mailing list on one or more PCs - decentrally - the list of members and, if necessary, the list of authorised senders can be maintained once centrally and used by several. Instead of being sent to several recipients, e-mails are only sent to one list address, and the resolution takes place on one of our servers.

Mailing lists are managed with the widely used Mailman software. They have rich web pages for administrators and subscribers with features such as:

  •     automatic subscription to lists to be confirmed by an administrator;
  •     private or public archive of posts to the list;
  •     Restrictions of possible subscribers and authorised senders via various filters and much more.

Documentation can be found at the GNU Project: GNU Mailman - List Administration Manual

If you are interested in a mailing list, please contact the helpdesk. State the mail address of the person who is to be responsible for list administration and the desired name for the mailing list.

No additional fees are charged to users for the service.
