# msp_nullclient.m4 m4 file for supporting a nullclient in the MSP
# environment.  That is, change the feature(msp) to feature(msp_nullclient)
# in /etc/mail/submit.mc.  An MTA listener is now optional, and you can
# run with only MSP mode (setgid mail).
#
# This file is blatantly cut&pasted from nullclient.m4 and msp.m4 !!!
#
# If you've a better idea, please let me know

#  that client does absolutely nothing else -- i.e., it is a "null
#  mailer".  In this sense, it acts like the "R" option in Sun
#  sendmail.
