Not really a good idea to reject all spam. Spam filtering is not that black
and white.
Suppose a legitmate email gets tagged as Spam.
This does happen trust me and more than likely its a email your boss has
been waiting for.
You'll want a some way to retrieve it.

I use mailscanner also, works great.

I delete whats called high scoring spam and deliver the low scoring spam.
Since the low scoring spam is tagged as spam.
You can either use mail client rules or a procmail receipe to move it to
another folder.
That way, the user can retieve it themselves.
