Mailman packages and configuration are managed by Puppet class hcoop::service::mail::mailman2

1. Migrating Mailman Between Servers

1. Copy /etc/mailman/{mm_cfg.py} to new server

   • vhost_cfg.py is generated by DomTool.

2. Copy /etc/exim4/mailmandb to new server

3. Stop mailman to prevent messages from being delivered while copying data: service mailman stop

4. Copy /var/lib/mailman to new server

5. In /etc/exim4/conf.d/main/01_exim4-config_listmacrosdef on:

   • the new mailman host: unset HCOOP_MAILMAN_RELAY_HOST

   • all other mail servers: set HCOOP_MAILMAN_RELAY_HOST to the new mailman host

6. Start mailman on new server: service mailman start

7. Reload exim, and everything ought to work

DomTool also needs some settings updated.

1.1. Move All Lists

The entirety of /var/lib/mailman can just be rsynced between servers. This is assuming Debian configuration where system controlled content and data like locks are stored in external directories and just symlinked from /var/lib/mailman.

2. Importing Individual Lists

Not entirely sure, but an old post on mailman-users might have some insight.

3. Change List Domain

If a member requests a change in the primary list domain

• LISTNAME is the bare list name (e.g. hcoop-discuss) NEWBASEURL is the base url, with no list name (e.g. lists.hcoop.net)

sudo -u list withlist -l -r fix_url LISTNAME -u NEWBASEURL

Mailman doesn't care about SSL, except for the list archive link, which is a template and can be edited through the web interface by the list owner.
