Aha! I get it now - nice feature. It would indeed be a good feature to have
as mailing list emails can be very frustrating especially when it comes to
web-based email products like the one we produce. The only way to track this
back from the headers is usually to look at the Received: header field. We
have built this into our code so that it can track back who the mail was
intended for. For example, from your previous post:

Received: from list.cobalt.com (list.cobalt.com [63.77.128.170])
	by www.ukwebs.net (8.9.3/8.9.3) with ESMTP id TAA30919
	for <sales@xxxxxxxxxxxxxxx>; Wed, 29 Mar 2000 19:51:04 +0100

Is the first Received: record in the header of the email and you can see
from this that it contains the for <email@address> element. This works most
of the time, but there's no compulsion for this to appear in the header.

I'll have a look around for the sendmail X-POP-3-Rcpt field.
