Syntax for Mail Archive and Monitoring Ruleset

[Ryan Pitt]

I have been searching around trying to find out what the syntax is for
the ruleset that allows me to get a copy of incoming and/or outgoing
emails from specific email addresses.  The feature is called "Mail
archiving and monitoring".
I gather that this file can be called 'anything' as long as it is
specified in MailScanner.conf
Please could someone let me know how the entries are to be made in this
file.
Thank you
