The mailman system (mailman.cchmc.org) which provides mail lists for CCHMC was upgraded to Mailman version 3 on 3/9/2022.
The old mailman system was version 2 which is no longer being supported or security patched.
To access your list settings you need to create an account on the new system. Please see the below instructions:
To access the settings or moderated any messages of your migrated mailman list (or lists) you need to follow the below instructions to create an account. This is because there is no longer a shared password to manage each list. Each list admin (or moderator) needs to create an account on the mailman 3 system to access any lists they administrator. Your mail list WILL NOT stop working if you do not set up my admin account. However, you will not be able to do any list administration (add users, delete users, etc..) or moderation until you set up an account.
Users on the lists do not need to set up an account on the mailman system to SEND OR RECEIVE emails from a list. sending and receiving emails will work exactly like it did on the old system.
users would only need an account on the system if they were accessing their individual settings for a list. If you had users (not admins or moderators) that were logging into mailman 2, please reach out to
To create an account go to http://mailman.cchmc.org/ and click the sign up button.
https://mailman.cchmc.org/ and click the login button
Then you can select the drop down 'filter by role" to filter the lists you are the Owner of.
Then click the name of the list to access the list settings.
The mailman 3 interface is laid out differently than mailman 2 but is still pretty intuitive, But I have created a site with some instructions if needed.
