# The users are instructed (in PORT_NOTES) to install ${QUEUE_DIR}/rc
# themselves.  Each /var/qmail/ should have its own rc.  On many machines,
# /usr/local/ is nfs mounted and /var/qmail/ is local.  An individual
# machine may want/not-want qmail.  Pity we can't add a dir to local_startup
# from here.

# Wouldn't hurt to provide an "enable_qmail" and "disable_sendmail" target
# that do 1) and 2) above and disable the existing sendmail, respectively.
