MailScanner on Exchange

[Martin Hepworth]

Risk....

Do a risk assessment of putting the MS-Exch system 'in the internet'. Look
at the threats and LIKELIHOOD of the threat which will give you the business
risk associated with doing this. 

That way you can make an informed choice, rather than get into a my dad is
bigger that yours type argument.

If you care to publish this after on the wiki (when it's back) that would be
nice too.
