Stop logging message over sacore 20

[Mikael Syska]

Hi,

We have a failrly large mailwatch db ... about 2 mill rows ... to
speed things up we could delete mesaage with a sascore over 20. that
could cut off 1.5 mill rows ... :-)

using:
SpamAssassin Rule Actions = SpamScore>20=>delete

But what about mailwatch? Do I need to edit the MailWatch.pm file or
can it be dont within MailScanner ?

best regards
