Hello,

I strongly recommend to everybody to include notification in case
of automatic re-lunch of milter-greylist.

Here is my /usr/local/etc/check_milter_greylist which is scheduled to run
every five minutes from crontab on SuSE LINUX:

#! /bin/bash
PIDLIST="$(ps axo ppid,pid,comm | awk '{ if ($1 == 1 && $3 == "milter-greylist") print $2}')"
if [[ x"$PIDLIST" == x ]]
then
  /etc/init.d/milter-greylist start > /dev/null 2>&1
  recipient=postmaster
  mailx -s "Milter-greylist restarted on $(hostname)" "$recipient" < /dev/null
else
 :
#  printf 'RUNNING: %s\n' "$PIDLIST"
fi

You may just use as it is replacing the recipient variable better fitting to your site.
It must be trivial to port to other platforms.

Bests,
Attila
