I've deleted all but the relevant Received lines that John posted....

As you can see, the headers correctly identify the intended recipient.
From this, I have concluded my IAP's sendmail is configured correctly -
that is, he's not tried to hide addressing information.
It's not a matter of hiding or correct configuration....
I don't understand your meaning.
In October 2001 I got this from one of the UML lists:
Received: from usw-sf-list1.sourceforge.net (usw-sf-fw2.sourceforge.net
[216.136.171.252])
by netsrvr.ami.com.au (8.11.2/8.11.2) with ESMTP id f94EpHJ01928

As you can see, the Received: header inserted by netsrvr.ami.com.au
identifies the subscription address correctly.
You're using listreader as your username on the UML lists?
I originally subscribed under the name listreader. When I established
the uml account for testing, I subscribed that.
However, in August I got this:
[from the user-mode-linux-user list]
Received: from usw-sf-list1.sourceforge.net (usw-sf-fw2.sourceforge.net
[216.136.171.252])

f77HCZh07433;
Wed, 8 Aug 2001 01:12:36 +0800
which does not have the 'for" clause in netsrvr's header. However, it
has worked with the UML account I created here:
[from the user-mode-linux-admin list]
Received: from usw-sf-list1.sourceforge.net (usw-sf-fw2.sourceforge.net

I guess the first question that needs answering is this;
How can an MTA send mail to sendmail in such a way it doesn't record
who it comes from?
Who it comes from, or who it's going to? I was following you up until
that question.
The "for" clause identifies the intended recipient. As I understand it,
it comes from the exchange between MTAs and so need not appear in TO:
or CC: headers (and is often different).
What I see happening is that for all but the user-mode-linux-user
list, you get a "for" clause added by netsrvr.ami.com.au telling who
the message is intended for (the envelope recipient). But on the
user-mode-linux-user list, you get no "for" clause.
Exactly.
The answer is simple. Someone else getting mail through
netsrvr.amu.com.au subscribed to user-mode-linux-user in August. If
there are multiple envelope recipients, sendmail does not add a "for"
clause. Otherwise the Received header could get huge.
Interesting. I've tested your thesis and it certainly works.
However, this message got delivered correctly to two different
addresses here:

However, you're probably right and the times it works are due to the
oddities of how the list manager or the MTA it talks to behaves.
