You want to set QMAILUSER and QMAILHOST (rather than the versions with
'S' after qmail). Those control the From: header. The 'S' versions
control the envelope sender.

Unfortunately, that doesn't produce the result I need. My local username
(greg) is not the same as the user portion of my Internet-reachable
mailing address (wooledge@kellnet.com).

Actually, I went out of my way to get it to do so. Recompiling pine
isn't the most enjoyable way to spend one's time. :-/

This is what I ended up doing; specifically, I set the QMAILSUSER and
QMAILSHOST variables to "wooledge" and "kellnet.com", respectively.

However, I wish to file a bug report: the man page for qmail-inject
clearly states, "The envelope sender address is normally the same as the
address in the From header field". In my testing, however, the 'From'
header field seems to be ignored. Either qmail-inject has a bug, or
the man page does. :-(

Relevant data:
qmail 0.96
Linux 2.0.28
libc.so.5.4.17
gcc 2.7.2.1

To reproduce the behavior (on my system):
$ unset QMAILSUSER QMAILSHOST
$ /var/qmail/bin/qmail-inject
From: wooledge@kellnet.com
To: greg
Subject: test

test
^D

I *wanted* to control the envelope sender. Note the Subject of this
message. :-)

My envelope sender was not correct for outgoing messages; ezmlm, for
example, uses the envelope sender. Until Russell told me how to fool
ezmlm into accepting my message (djb-qmail-subscribe-wooledge=kellnet-com),
I couldn't even subscribe to this list -- because my envelope sender was
wrong.

Doh, I feel rather stupid now :-) I saw something about From: and didn't
really read the rest of the message.

I went back and tried to reproduce your test. Here's what I did:

$ /var/qmail/bin/qmail-inject
From: evanc@qlist.synapse.net /* defaulthost = synapse.net, qlist is
separately delivered to handle my
mailing lists */
To: nonexistent@synapse.net /* on my main mail server, user doesn't exist */
Subject: test

It bounced back to evanc@synapse.net, not evanc@qlist.synapse.net. This
backs up your result where the sender wasn't set to the From: as the man
page states.

I'm not sure if I consider it "wrong" (in that sendmail does the same
thing unless you specifically give it a sender via -f), but it should at
least be consistent with the manpage. Since qmail doesn't try to enforce
the sender, it might as well use the From: verbatim unless it is given
other instructions.

What this means is that the default envelope sender is the same as the
default From address. Either one can be overridden by incoming fields.
