# Since FreeBSD does not supply a user for running an MTA in a sandbox
# by default, use user 'exim', adding it if it does not exist.  Even
# if FreeBSD supplied an MTA user, it's neglected to do so for so long
# that every sandboxed MTA under the sun uses its own user, so user
# 'exim' should probably be used forever.
#
# Modern FreeBSD systems already have a group mail.
