I just tried to check about error messages on my list and received the
strangest set of messages. The first indicated at a Rochester
distribution point that the message had never gotten to the list site.
In five minutes, I received the error messages for the post which
according to the first message did not get to the site. The problem
seems to be the mailer daemon or demon system. I understood this to be
an automated gating system developped at Cornell, but it seems to be
linked to a group of postmasters and network administrators who use
the daemon software or designate themselves by this name. I always
assumed that it checked the addresses. Could someone explain this
system to me and why it is the major cause of my worst mailing problems?--Paul.
