Getting rid of Postmaster Notify

This is your mailer doing this, not MailScanner. Default behaviour.
You _could_ link it to /dev/null but please be aware that its also the
mailbox used for example when you get abuse mail normally.

You could setup a rule to shift those out, or for example edit the alias
file on your system and let those come in a seperate 'dev/null' box. Then
you dont loose regular postmaster mail.

Bye,
Raymond.
