I changed the entry in my /etc/aliases to point to a perl script:

-----------------------------------------------
#!/usr/bin/perl
use Mail::Audit;
my $mail = Mail::Audit->new();

#
# Filter criteria goes here...
# If mail is to be /dev/nulled,
# $DUMPIT = 1
#

if ($DUMPIT == 1) {
        $mail->ignore;
        } else {
        $mail->pipe("/usr/local/bin/listserv/lsv_amin 
/app/listserv/spool $ARGV[-1]");
        }
exit;
------------------------------------------

So that unwanted mail never hits the Listserv application.

Am I incorrect in thinking that "Send= Private" would still generate 
emails to the "originating" (probably spoofed) address that says "You 
are not authorized to send to the XXX list from your user@host account..."?
