I do this differently. I just run a daily cron does something like:

#! /bin/bash
/home/mark/.cron/get_memb | \
/usr/local/mailman/bin/sync_members -w=yes -g=no -a=no -f - gpc-announce

get_memb happens to be a python script which uses the MySQL-python
package <https://pypi.python.org/pypi/MySQL-python/> to access the MySQL
database and extract a list of

First Last <email>

entries for all current members of my bike club from our database and
gpc-announce is the "all club" announcement list.

The get_memb script is specific to our database, but it could basically
be anything, even just a straight MySQL query, that produces the desired
list (In our case, the logic of determining whether a record in the
table is that of a current member is complex and in some cases involves
looking at dates in other records, thus the python script).

If you want to do this via a triggering email as you propose rather than
cron, you could still use a shell script such as mine and invoke it from
your handler, or skip the script and just invoke something to get the
list and then invoke sync_members on the list
