[ih] spam filter bug fixed

[Joe Touch]

Hi, all,

FYI, the bug was in procmail, where a character that was previously used 
to delimit words wasn't valid anymore.

I.e., we had rules that include "hold all 
(petroleum|nigeria|angola|etc...)" - which I manually check - but the 
rule was getting ignored.

It is now getting caught. Thanks everyone for the numerous fixes 
suggested, but this one just turned out to be a bug... ;-)

Joe
