I use a script to get a cunnect list of users in differnet groups into
a file and then use sendmail with /etc/aliases
<-cut- /etc/aliases>
# Put any sendmail aliases in here
# Rember to run `newaliases` after adding
postmaster:root,chris
admin: chris
everyone: users,staff,pusers
# list of group files
users: :include:/home/chris/scripts/mailusers/users
staff: :include:/home/chris/scripts/mailusers/staff
pusers: :include:/home/chris/scripts/mailusers/pusers
<-end cut->
when adding a file as a aliases make sure its chmod +r
the script only requires a few setting and then will make a file for
every group in the LISTGROUPS file
<-cut- /usr/local/sbin/usermail>
#!/bin/sh
# /usr/local/sbin/usermail v1.2
# Reads the LISTGROUPS file and then makes a file named after each group
# listed using the /etc/groups and /etc/password file first field
# to creates a mailing list file from all the usernames.
# It only places a user in the first group ( groupid in /etc/password )
#
# best run by cron from time to time
# 17 1 * * * * /usr/local/sbin/usermail 1>/dev/null 2>/dev/null

the LISTGROUPS file should only have one group per line

I have a second script that dose this live but found that when its run
with 300 users and several mails at a time my old mailserver (386) got
real bogged down
