Doesn't recognize this either.

if (isin(From,HIDDEN@bay.com")) call spamdetect(-22.0,"")

I must be just on a totally different page. The documentation examples don't work. I'm getting pretty discouraged. I'm almost sorry I "Upgraded" to Surgemail.

Doesn't ANYONE use filters of any kind?

Simple.dat --> Simple.rul --> mfilter.rul --> doesn't recognize
Friends.rul --> totally ignores

Any other ideas?
