I have both going on, actually.  I have filtered nearly everything I can
on the front end.  I can add a white list filter on the front as well,
but it will be less flexible than if I just write what I want...

Unfortunately, my Perl is rusty and it pisses me off nearly as much as
the spam.

I'm up to over 800 spams a DAY for a dozen or so messages of any import
and many 50 mailing list entries.  It is making my heart burn in anger.
 I HATE IT.

Since I applied for financial aid for college the spam is THROUGH the
roof.... the bastards sold my information to every spammer on
earth...because what do they give a shit.  It is just another fucking
scam to twist your gonads in a vice and exploit you.
