sendmail runs as root for the rather obvious reason that it needs to bind a socket to a restricted port number (25 == SMTP). Before sendmail exec()'s any processes, it does a setuid() to UID 1, which is daemon. None of the virus processes running on our system ran as root; rather they ran as daemon. Let's not flame sendmail for having the DEBUG command. It actually is a rather useful tool. Instead of removing the DEBUG command, simply change the 3 lines of code that check for a particular debug flag being set, and allowing mailing directly into programs, files and :include: lists.
