This may not be the best method but it works for me today and for Annette
Deschon who manages the gateways that respond to mail for Telemai/Mcimail/
Dialcom.  We scan the From: line for one of the following character strings:

MAILER SMTPUSER DAEMON DATABASE POSTMAN POSTMAST MMDF SUBSYSTEM

If the From field contains one of these character strings the mail is
placed in a holding area and is not processed until there is some
human intervention.  I would prefer to see a special RFC header that
indicates that the mail being received was created by a program and not
by a human but I guess that will never happen.  In the meantime, this
works for Database@Bitnic.Bitnet and has stopped countless loops between
networks and within Bitnet.
