Or, using "new math", 0000000000000000000000001.7%. <G>
We see a hit rate here of about 29% (or "000000029%" or "00000.29") on our
"BADHEADERS" test, which only catches broken E-mail, so it is quite
effective against stopping spam. So while filtering on headers is likely a
waste of time, testing the headers for validity is a very quick process
that is quite effective.
