I have blocked these subjects in Sendmail thanks to a post by another list member. http://list.cobalt.com/pipermail/cobalt-users/2003-July/093705.html
Thanks for the link, but ugh -- that message is a mess! (html, of course) I cleaned it up a tad and made a PDF for easier reading:

Subjects I'm blocking: Warning about your e-mail Notify about your e-mail Notify about using the e-mail You use illegal File Sharing And for the clueless useless virus notifications: You sent potentially unsafe Network Associates Webshield Virus found in a message you sent Virus was detected Your mail server sent us a virus
Anyone got the .mc "magic entries" for this type of thing that will prevent hand editing of sendmail.cf?
