or if i'm not mistaken regexp/pcre files are scanned top to bottom looking for a match. move the jp filter line to the very bottom. then place something like this just above it /\.groups\.yahoo\.com/ OK thus any message with groups.yahoo.com in the header will skip the jp filter, but it will apply to everything else so it keeps "some" effectiveness. (thats what i've been doing, moving any rules that trigger yahoo groups below that OK line )
