i am guessing i would just need to tell openacs where qmail-inject is, but this is just a guess, i and i wouldn't know where to do this. It seems like with sendmail it knows to look at /usr/sbin/sendmail.
AOLserver doesn't call /usr/sbin/sendmail (or qmail-inject). It simply tries to establish an SMTP connection with whatever IP you've declared to be your "mailhost" in the nsd.tcl file.
In your case, this appears to be a machine called "officenet". Are you sure that qmail is accepting SMTP connections on "officenet" from whatever machine AOLserver is running on in your local network?
AOLserver doesn't care what your SMTP server is running. It just ships the mail off to port 25 on the configured server, that's all. Plenty of us us qmail here so that's not an issue.
Perhaps the /etc/hosts file on the webserver machine isn't set up with an entry for "officenet"? Maybe qmail's set up to not relay from other servers on your LAN?
The above are just wild guesses.
