Status

Experimental.

Overview

This is GNU Mailman, a mailing list management system distributed under the terms of the GNU General Public License (GPL) version 3 or later. Mailman is written in Python which is available for all platforms that Mailman is supported on, including GNU/Linux and most other Unix-like operating systems (e.g. Solaris, *BSD, MacOSX, etc.).

Post-installation steps

Setup Admin User

You must configure the admin user:

$ cd /usr/share/mailman3-web
$ python3 manage.py createsuperuser

You should then attempt to log in with this user account in the web UI. Once you've logged in, a confirmation mail will be sent to your email address that you specified. Therefore, you should have something like Rainloop installed to view mail on your YunoHost installation.

Setup your main domain

You'll need to log in as administrator and visit the /admin/site/site.

If you're Mailman3 is setup on myyunohost.org then that would be the following:

myyunohost.org/admin/site/site

Configure Postfix and LMTP

Mailman3 implements an LMTP server for receiving mail from Postfix. This means that Mailman3 doesn't need anything from Dovecot. This is important to understand because Dovecot is the default YunoHost local delivery agent. Therefore, the default YunoHost Postfix configuration uses Dovecot. So, in order to deliver incoming mail, we need to override which delivery agent handles which mails based on the addresses. In other words, if you create a mailing list "mylist@myyunohost.org" you want Mailman3's LMTP server to receive this, not Dovecot, becaues Dovecot only delivers to LDAP created user accounts.

You'll need to add this to your Postfix configuration:

owner_request_special = no

transport_maps =
  hash:/var/lib/mailman3/data/postfix_lmtp

local_recipient_maps =
  hash:/var/lib/mailman3/data/postfix_lmtp

virtual_mailbox_maps = ldap:/etc/postfix/ldap-accounts.cf, hash:/var/lib/mailman3/data/postfix_lmtp

And then run:

$ mailman aliases

This is unfortunately a manual step at this point because the package remains experimental. Once it matures, this will be integrated into a hook or the default Postfix configuration. For now, remember that when you run yunohost tools regen-conf postfix or if any installation invokes regen-conf, your Postfix configuration will not be changed because it has diverged from the default configuration. This may cause you problems if YunoHost core expects that there is some new value in your Postfix configuration.

General Configuration

Mailman3 is made up of 3 moving parts:

• Mailman3 Core: https://mailman.readthedocs.io
• Postorious: https://postorius.readthedocs.io
• Hyperkitty: https://hyperkitty.readthedocs.io

There is also documentation for "the suite" which is all the parts together:

• https://docs.mailman3.org

On your YunoHost, all the configuration files you need to worry about are in:

• /etc/mailman3/

It is important to note that this package makes use of the mailman3-full Debian package contained in the Debian Stretch backports repository.

Finally, you also configure things through the Django web admin available at /admin/.
