Thanks for the reply.

Hmm. Well, the qmail-smtpd man page says:
"... qmail-smtpd must be supplied
several environment variables; see tcp-environ(5)..."
and the man for tcp-environ lists TCPREMOTEINFO:
http://www.qmail.org/man/man5/tcp-environ.html
> It doesn't hurt to get it and log it,
And how would one do that? Does it show up when you run qmail-smtpd with
tcpserver's -v option?

I see. Well, we're an ISP, and remember that while half our SMTP mail
(outbound mail) comes from desktops like you said, the other half (ie,
incoming mail) comes from other SMTP relays around the world.
I'm open for more input. Can anyone else comment on how else a blank
$TCPREMOTEINFO will affect our qmail logs, headers, etc?
