Creating new System users for Panther and Postfix
If you use radmind to upgrade a machine from 10.2.x
to 10.3, several system users will not be created (unless the NetInfo database
is not in your negative transcript). Without these users, postfix (the new mail
transfer agent - it replaces sendmail) will not work. Other services may also
be affected. Here's how you can automate creating those needed users and
groups.
This fix was made easier by poking around on the
Panther Install disk 1, looking at the Install packages, and looking at the
scripts buried in the Resources. There is one called CreateSystemUsers that
served as the basis for this script. Again, I run this as part of a custom
StartupItem.

This last bit is not strictly related to the creation of missing system users, but if you want Postfix to operate as a way for processes to send outgoing mail to an external mailserver, you'll need to make a change to the /etc/hostconfig file:
##################################################################
# turn on postfix-on-demand in the hostconfig file
##################################################################
if [ "${MAILSERVER:=-NO-}" = "-NO-" ]; then
echo "Starting Postfix"
cp /etc/hostconfig /etc/hostconfig.bak
grep -v MAILSERVER /etc/hostconfig.bak > /etc/hostconfig
echo "MAILSERVER=-AUTOMATIC-" >> /etc/hostconfig
# start postfix to create the needed directories and pipes in /private/var/spool/postfix
/usr/sbin/postfix start
# now we can stop postfix
/usr/sbin/postfix stop
# finally start the mail queue watcher
/usr/sbin/postfix-watch
