There is a big difference between what one can filter in 8.8.8 and 8.9.0.
I ran my own and later Claus's Assman's *.mc stuff on 8.8.X. Under
8.8.8 you can't filter on (internal) header data. Thats a *very* big
lose. Check your spam sometime and see how many realy easy kills you
get by filtering on any of the following headers:
To: friend@public.com
X-UIDL: *
X-PMFLAGS: *
X-COMMENTS: Authenticated sender is *
DATE: x________*
X-MAILER: <one of several spam mailers>
Back when 8.9.0 came out the spam filter rate of the above tests alone
was well over 90%.
