This took me a little while to get right. I use listserv 1.8d and qmail.
rcpthosts has all my usual aliases: localhost, listserv.domain.name,
eachmachine.domain.name, etc.
Then for relaying, I have my entire local subnet in /etc/hosts.allow:
tcp-env: my.sub.net. : setenv RELAYCLIENT
and smtpd in inetd.conf:
smtp stream tcp nowait qmaild /path/to/tcp-env tcp-env
/path/to/qmail-smtpd
The trick is to make ABSOLUTELY sure that -DPROCESS_OPTIONS is enabled for
tcp wrappers. Even if you think it is, double-check it.
