Wow! You really wrote all that in just 20 minutes?? Looks complicated!

If I am not mistaken, the hourly cron job will not bite, some time ago it 
was made intelligent I believe and now checks if MailScanner was not 
stopped purposely, if it was, it will not restart MS.

Thanks again!!!   This is a real life saver, especially I am on holiday 
and they call me and I have to explain how to stop MS on one box to get 
outgoing mail working again.
