# In many systems nowadays this uses Name Service Switch, which is

# args = uid=500 gid=500 home=/var/mail/%u

# LDA and LMTP needs to look up users only from the userdb. This of course
# doesn't work with static userdb because there is no list of users.
# Normally static userdb handles this by doing a passdb lookup. This works
# with most passdbs, with PAM being the most notable exception. If you do
# the user verification another way, you can add allow_all_users=yes to
# the args in which case the passdb lookup is skipped.
