Mailman email distribution lists to be retired

Mailman will be retired from 2 March 2020 and emails sent with addresses will no longer be delivered. We’ve have had a good response by contacting administrators of Mailman lists and so far 145 lists have been migrated. If you still use Mailman lists, get in touch, so that we can help you move to a different solution.

Mailman ( will be retired at the end of February 2020. We are contacting Administrators of Mailman lists to let them know and provide support to move to use alternative solutions, if required.

If you don’t need a Mailman list any longer:

  1. Send an email to members of your Mailman list to inform the them that this list will be retired
  2. Login to your Mailman lists from
  3. Click Delete this mailing list from the menu

However if you need to contact colleagues in the same way as before, we can help you to setup and use one of these options:

  • Email distribution group – for University staff and students only
  • JISC mail for collaboration with external members, providing a similar experience to Mailman lists
  • Yammer – option to create a private discussion group for University staff and students
  • Team Collaboration Space – for messaging and file sharing within a team of University staff and students

Contact the IT Service Desk for advice on the option most suitable for you.
