Increased SPAM getting through

[Duncan, Brian M.]

We have a backend active directory server that exports ALL SMTP aliases
for users every hour.

I import this list at all sendmail/Mailscanner/SpamAssassin boxes.  It
gets built into the access file, all
Addresses from AD are allowed to be sent to, all others are rejected.

Originally I combined the methods I found on the Wiki I believe.  There
was an example VB script to export aliases from AD if needed.
