The folloing is from a mail transported by the RedHat 7 powertools exim: Received: from localhost.localdomain ([127.0.0.1] helo=localhost ident=tori) by boris.prodako.se with esmtp (Exim 3.13 #1 (Debian)) id 13gk0J-0000QW-00 for <tori@localhost>; Wed, 04 Oct 2000 10:34:19 +0200 It shouldn't say Debian, should it? :-)
Ahh... I now see where it comes from. It is the (excellent) configuration script /usr/sbin/eximconfig that contains Debian, and adds it to the configuration file.
