Here is my csh ping script. You'll have to change the name of the mailer program to fit your system: /usr/andrew/etc/queuemail -f pingmail -a mg5n+@andrew.cmu.edu hfinney@shell.portal.com catalyst@netcom.com elee7h5@rosebud.ee.uh.edu nowhere@bsu-cs.bsu.edu remailer@chaos.bsu.edu hh@cicada.berkeley.edu hh@pmantis.berkeley.edu hh@soda.berkeley.edu ebrandt@jarthur.claremont.edu remailer@merde.dis.org And in the file pingmail I have: To: remailer-list From: Automated Mailing Script <mg5n+@andrew.cmu.edu> Subject: Ping :: Request-Remailing-To: mg5n+@andrew.cmu.edu ----- This is a Automated Remailer Ping Message ----- I have one copy sent back to myself so I get a timestamp of when it went out. You can set the To: line if you want, but most systems don't need it.
