Here's your problem.
From "man sendmail":
-F full_name
Set the sender full name. This overrides the NAME environment
variable, and is used only with messages that have no From: mesâ
sage header.
-f sender
Set the envelope sender address. This is the address where
delivery problems are sent to. With Postfix versions before 2.1,
the Errors-To: message header overrides the error return
address.
You need to set the envelope address.
sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED]
Thanks much, Sandy. That was the key -- but I'm not quite there yet. The
lines:
suillus:~ # sendmail -f [EMAIL PROTECTED] -F [EMAIL PROTECTED] [EMAIL PROTECTED]
xxxyz
.
caused me to receive the following message:
From: "[EMAIL PROTECTED]" <[EMAIL PROTECTED]>
To: undisclosed-recipients:;
xxxyz
So I'm getting mail at last -- but the "from" and "to" aren't there.
Of course not, where should they have come from? (^-^)

That is how the server sees the SMTP submission of a mail.
In your example you haven't set the header lines from: and to, so the
Postfix daemon "cleanup" inserted the necessary headers. If no from:
header is set cleanup will use the smtp envelope address as from: header,
if no to: header is set, Postfix will use "undisclosed recipients".
As you can see the addresses in the mail header are not very reliable. (^-^)
