How to Remove X-headers

[Glenn]

Oh, sorry, I did not read Joost's post carefully enough to see the difference 
between his expression and mine.  However, I just tested his expression, /^X-
Mime.*\:/ , and it doesn't work either.  I am wondering if MailScanner can 
use Perl expressions in this ruleset?  Thanks again.   -Glenn.
