Anita, I have seen all of these peculiar messages. All of the mailer daemons are people. Everyone that I have ever looked for has been a person. It is some sort of network of individuals, although it is supposed to be an automated system. I don't know whether you will get an answer because of their profiles. I have a feeling that mailer daemon is going to be some sort of news story one day at times. Good luck with your inquiry. --Paul. -- Dr. Paul S. di Virgilio, University of Toronto [log in to unmask]
