I also maintain various web sites which use MySQL to maintain information about users. I often need these user to be subscribed to mailing lists based on groups or other attributes stored in the database. The following script, called regurlarly with a few appropriate parameters will do just that :

#! /bin/sh
# mmsql: An sql extractor for mailman
#
# Usage: mmsql      []
#   is the name of and existing mailman list
#   is the name of an existing mysql db
#   is the username to login to mysql
#   is the password to login to mysql
#   is the select clause to run
#   are the parameters passed to mailman's sync_members command
#     defaults are : -a -w=no -g=no
#
# Example :
#   mmsql MyList MyDB user password "SELECT email FROM users"
