This is correct. There are lots of programs/scripts that call either /usr/lib/sendmail or /usr/bin/mail when they want to send an email message. I remember seeing somewhere that '/usr/lib/sendmail is the standard place to look for a sendmail executable' - this is either in the debian policy, or the file system heirarchy. Either way, it implies that every fully functional system have a functional /usr/lib/sendmail. Carl
