===== Fix postgrey Restart =====
After you have fixed the [[tips:fix_postgrey_pid|PID problem]], you'll notice that "service postgrey restart" still does nothing. To fix it:
  # nano /etc/init.d/postgrey
comment out almost everything in the do_stop section, and limit it to just these two lines:  
  kill `ps aux | grep postg | egrep -v "(restartpostgrey|grep)" | cut -d " " -f 2`
  rm -f $PIDFILE
