ICT will not support the creation of new GNU Mailman Lists after Thursday 31 August 2023. If you require a new mailing list with external users, we recommend creating an Office 365 Group.

A Mailman mailing list is:

  • Managed via a web-based interface and/or email-based commands;
  • Supports internal and external (i.e. non-Imperial) addresses;
  • Populated with a rich feature set of both list and user-based preferences (e.g. list archiving, digest mailing).
  • Often used for newsletter sends to societies

We would advise users to use an Office 365 group over Mailman distribution lists, as they offer more functionality such as shared calendars, file storage and are far more secure as they use your Imperial password.

If you would still like to use a Mailman mailing list, complete our online form in ASK.

You can hide your mailing list from the list above, by going to the Privacy options section of the list administration site.

Mailman passwords

  • Passwords are set per list (for configuration, administration and moderation). Each member of each list has a separate password for each list they belong to.
  • These passwords are not secure and they are not your College password.
  • The default action of lists is to send the password to the relevant member's email address once a month as a reminder of the membership to the list. They are used to control access to user-based list preferences and list archives where applicable.
  • The web interface provides detailed explanations for each configuration option available.
