	a digest should never bounce back to the list.  all mail from 
majordomo should bounce to either the postmaster or majordomo-owner or 
the list owner.  your outbound headers are incorrect.

	yes, all incoming messages go to either majordomo or resend.  i 
have patches for both.

resend:  after line 226

                        ||   ( $1 =~ /repeat as required/i ) ) {
                               &bounce("Kill Filter");
                        }
