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..."? -CW A.
