We are writing an automated mail forwarding program for Microsoft mail.
One option will be to send a message back to the sender notifying them
of the changed address.  We would like to be sure that such messages
will be captured by the LISTSERV filters, even for Safe=no lists.  I
know that LISTSERV looks for subject lines that begin with "undeliver".
What other words does it look for?
