	If you look at SMTP level, the used MAIL FROM envelope
	is in reality:

	It is the local delivery 'mailbox' program which in this
	special case claims 'MAILER-DAEMON' as message source at
	the From-space header line.

	At the Mailbox there is also header:
	        Return-Path: <MAILER-DAEMON>
	in this error case.

	What is the application for this "From-space" header contained
	address ?  UUCP ?
