I'm having trouble picking a specific header in Outlook 2000
and then matching another part of it.  However it is easy to
match one fixed string in any header that can include the
header name. I think I'll add a new header with just the *'s
to make it a simple match for any threshold, and perhaps you
should consider that in the default filter.  I suppose it would
break existing procmail settings to move the number to the other
side of the *'s.  Outlook Express doesn't want to look at
special headers at all, but considers the attached report part
of the content in rules, so maybe the line should be repeated
there.
