That would be handy, although you thought you could already do this after a
fashion by setting the option to not scan messages that already have the
MailScanner header.  Looking through the conf file I can't find it - was it
in another product?  Essentially it was a header that said to skip scanning
if it already had been as it was clean.

Of course, a spammer could spoof that, but it doesn't seem all that
profitable to do so, as my custom header value will differ from yours, so
the spammer would have to know what they all were and target their spam

By the way Lindsey, you may want to reset your reply to address.  It
defaults back to you instead of the list.
