You are basically correct. The key thing to remember is "Don't kill -9
MailScanner processes". If it is given a normal kill command it will finish
the clearup before exiting and leave your queues intact. If you kill -9
then I can't clearup at all and therefore half a message may be left in the
mqueue.in. The best way to stop it is using the init.d script which shuts
everything down cleanly. If you kill the main "parent" MailScanner process,
or else kill all the MailScanner processes, use a normal kill command and
then wait 5 - 10 seconds for the clearup to complete before using ps to see
if they have all gone. Don't expect them all to instantly die, they are
trying their best to clearup your system at that point.
