That is not a good way to do it. Because \/ is "greedy to the left", the
"[$WS]+" is equivalent to just "[$WS]", so you can end up with a $MATCH
that starts with whitespace. (And if there would be no whitespace
following the colon, $MATCH would not be changed.)

This is what everybody else uses:

   * $ ^To:.*\/[^$WS].*

thank you, right, I will be sure to use that instead for now on. I am
just wondering why

* $ ^To:.*\/[^$WS].+

won't work.

rob.
