Although I haven't tried this I think the following line in inetd.conf
would do the trick: (from 4.3BSD, SunOS 4.0.1 might differ)
smtp tcp stream nowait nobody /usr/lib/sendmail sendmail -bs
[You say you have tried some, but don't tell which] Essentially this
means: 'if somebody connects on port smtp/tcp run 'sendmail -bs'. The
argument -bs makes sendmail talk smtp on the stream-connection. (Don't
forget to kill -HUP inetd)
One drawback: since you're not running a sendmail daemon, mail that cannot
be delivered directly, will be queued locally. This can be fixed by adding
a line which runs /usr/lib/sendmail -qv every day or hour.
