A certain amount of scrabbling around in old folders (well, one doesn't
usually *keep* failure reports, does one?) suggests that Smail produced
headers like this
From MAILER-DAEMON Mon Mar 18 10:15:04 1996
Received: from ursa.cus.cam.ac.uk
by ursa.cus.cam.ac.uk with bsmtp
(Smail-3.1.29.0 #77) id m0tybxv-00011YC; Mon, 18 Mar 96 10:15 GMT
Message-Id: <m0tybxv-00011YC@???>
Date: Mon, 18 Mar 96 10:15 GMT
From: <MAILER-DAEMON@???>
To: root@???
Subject: mail failed, sending to address owner
Reference: <m0tybxu-00011kC@???>
Also, I notice that regexp_From (set in exim.c, used in accept.c) doesn't allow
for the sender field being empty --- or for it to contain spaces, for that matter.
