My changes are pretty much the same as yours, though I will implement
your patch again next time I test. For now I'm trying to make my own
qmail-env-scanner script work - I can see the from and rcpt-to
addresses, but for some reason the TCPREMOTEIP variable is invisible to
me. I'm still investigating this (and yes, I'm using tcpserver. However,
there should be a way to get this value even if you don't use tcpserver,
and that should be independent of what mechanism is used to launch
qmail-smtpd (inetd, tcpserver, foreground server, etc.).
