Mailman configuration notes
The mailing lists are now running with the standard Debian packaged version of Mailman.
The Mailman setup for Exim is in /etc/exim4/symbiosis.d/20-routes/11-mailman and /etc/exim4/symbiosis.d/30-transports/11-mailman. It's standard Mailman/exim setup.
LongSig
There is one non-standard extension, the LongSig handler. I have copied the Python code for the LongSig handler into /usr/lib/mailman/Mailman/Handlers.
LongSig is currently enabled only on accu-general. The process is described in this Mailman FAQ item. The input filename for the modified accu-general pipeline is in /etc/mailman.
Creating a new list
Given the appropriate Mailman login, you can create a new list from the web interface.
Unfortunately, it appears that while the list is created, some of the list files lack the correct permissions.
# chown -R list:www-data /var/lib/mailman/archives/private/<list-name>*
appears to be necessary.
