Key Differences Between Mailman 2 and Mailman 3

Mailing list system upgrade from Mailman 2 to Mailman 3 takes took place on June 17, 2025.

Authentication Has Changed

In Mailman 3, there are no longer separate list-specific passwords for either list members or administrators. Members of the university community log in to the interface using their TUNI credentials, while others create a local account for login purposes. After logging in, users can see all their lists, regardless of their role(s) on those lists. Password reminders are no longer in use, but users outside the university community can request a link to their email address to reset their password.

New List-Specific Role: "Non-Members"

Each list can have users in four different categories: Members, Moderators, Owners, and Non-Members. The first three are familiar from Mailman 2. The new "Non-Member" category is automatically created when a message is sent to the list from an address not associated with any list user. The sender’s address appears in the list owner’s "Non-Members" view, where the owner can manage settings for that address just like a regular user can manage their own settings. Additionally, the owner can assign a moderation setting to that address, which will then apply to all future messages from that "Non-Member."

Changes in Managing Individual Member Settings

In Mailman 3, user settings management changes in two ways:

  1. A single login allows users to modify both their general Mailman settings and list-specific settings for each list they belong to.
  2. List owners can no longer set default settings for new members of their list. Instead, they must configure settings individually for each member. Owners have access to the same settings as regular members and can also assign a moderation policy for each user.

Archiving Feature Removed

The new environment does not support list-specific (or any other) archiving capabilities.

Automatic Deletion of Messages Awaiting Moderation Has Changed

In Mailman 3, it is no longer possible to set a list-specific time limit for how long messages awaiting moderation are retained. A single, system-wide limit of 14 days applies to all lists.

Frequently Asked Questions for List Members / Subscribers

I have a TUNI user account – how do I log in to the Mailman 3 web interface?

As a TUNI user, you can log in to the web interface as follows:

  1. Go to https://lists.tuni.fi/mailman3.
  2. Click on “Login” in the top right corner.
  3. Click the “TUNI-login” button.
  4. Sign in using your TUNI email address and TUNI password.

Note: In the Mailman 3 web interface, your username will appear in the format username [at] tuni.fi.

I don’t have a TUNI user account – how do I log in to the Mailman 3 web interface?

You can access the web interface without a TUNI user account, as long as you first create yourself an account in the system. You can create an account as follows:

  1. Go to https://lists.tuni.fi/mailman3.
  2. Click on “Sign Up” in the top right corner.
  3. Enter your email address in the “Email” field.
  4. Re-enter your email address in the “Username” field (your email address will also be your username).
  5. Choose a password and enter it in both “Password” fields.
  6. Click the “Sign Up” button below the fields.

If the system shows an error saying “A user with that username already exists,” it means an account has already been created for that email address. In that case, refer to the section below: “I don’t remember my password, what should I do?”

Once your account has been successfully created, you can log in to the system as follows:

  1. Go to https://lists.tuni.fi/mailman3.
  2. Click the “Login” link in the top right corner.
  3. Enter your username (which is also your email address) in the “Login” field.
  4. Enter your password in the “Password” field.
  5. Finally, click the blue “Sign In” button.

I don’t remember my password, what should I do?

You can request a password reset from the system as follows:

  1. Go to https://lists.tuni.fi/mailman3.
  2. Click the “Login” link in the top right corner.
  3. Click the “Forgot Password?” link.
  4. Enter the email address you use to log in in the “Email” field.
  5. Finally, click the “Reset My Password” button.

You will then receive an email from the system—follow the instructions in that message.

How do I edit my account settings?

Once logged in, click your username in the top right corner of the interface and select “Account”, or go directly to https://lists.tuni.fi/user-profile/.

How do I edit my list-related settings?

Once logged in, click your username in the top right corner and select “Mailman settings”, or go directly to https://lists.tuni.fi/mailman3/accounts/subscriptions/.

The default view (Subscriptions) shows all the lists where you have a role. You can also view and edit other settings via the tabs: Global Mailman preferences, Address-based preferences, and List-based preferences.

How can I see all the lists where I’m a member or have another role?

See the answer to the previous question.

How do I contact the list owner?

You can contact the owner(s) of any list by email. The address format is:

listname-owner [at] lists.tuni.fi

Replace listname with the part of the list’s address that comes before @lists.tuni.fi.

How do I find out who the list owner is?

The personal email addresses of list owners are not publicly visible. However, you can contact them using the special address mentioned in the answer to the previous question.

How can I subscribe to a list I’m interested in?

There are two types of lists:

  • Some lists are updated automatically once a day based on data from other systems.
  • Others are managed manually by the list administrator.

In the first case, you can contact the list owner by email. If they determine that you should be added, they will handle your subscription.

In the second case, go to the list’s page at:

https://lists.tuni.fi/mailman3/lists/listname.lists.tuni.fi/

Replace listname with the part of the list’s address before @lists.tuni.fi, and submit your subscription request there.

How do I unsubscribe from a mailing list?

While logged in, go to the list’s page at:

https://lists.tuni.fi/mailman3/lists/listname.lists.tuni.fi/

Replace listname with the part of the list’s address before @lists.tuni.fi, and click “Unsubscribe”.

Frequently Asked Questions for List Administrators

Why did I receive a message titled “Uncaught bounce notification”?

Each mailing list has auxiliary addresses like listname-<something>@lists.tuni.fi. One of these is listname-bounces [at] lists.tuni.fi, used for processing bounce messages (delivery failures). These are typically system-generated and formatted for Mailman to handle automatically.

If a non-bounce message is sent to this address, Mailman doesn’t know how to process it and sends a notification to the list administrator. Thus, an “Uncaught bounce notification” usually means someone accidentally sent a message to the bounce address instead of the list’s main address.

Why are members of my list receiving "Your subscription has been disabled" messages?

There can be several reasons for this. One of them is the DMARC policy of the email service used by a non-TUNI list member posting to the list. The symptoms in this case are:
  • Messages sent to the list from within TUNI community are delivered to list members, but messages sent from one or more external organizations are not.
  • Several list members receive a message around the same time stating that their subscription has been disabled. When checking the address details of these members via the browser interface, the "Delivery status" of the address has changed to "Disabled by Bounces". 
 
If the above signs are present, the issue can be resolved as follows:
 
  1. Go to the “Settings” tab.
  2. Select “DMARC Mitigations”.
  3. Under “DMARC mitigation action”, select "Replace From: with list address".
  4. Click “Save changes”.

In addition, the disabled subscriptions need to be re-enabled. This can be done either by the list owner (for all members) or by individual members (only for themselves). The latter requires the member to log in to the browser interface (and if necessary, create an account, especially if the address is not a TUNI address).

I tried to subscribe or remove a large number of members at once, but the browser gave a "Proxy Error" message – what should I do?

If you try to subscribe (via "Mass subscribe") or remove (via "Mass removal" or "Remove ALL members") thousands of members at once, the operation may time out. In that case, the browser will report a "Proxy Error", stating "Error reading from remote server" as the reason. What this means is that the server managed to subscribe or remove some of addresses, but not all of them.
 
The "Proxy Error" situation is not permanent and does not "break" anything. Therefore, after the error message, you can simply check how many members are on the list and then repeat the mass operation with the remaining addresses.
