I've tried setting this line a two different ways.
Other DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl yields an SMTP connection refused message.
Other DAEMON_OPTIONS(`Port=25,Addr=192.168.0.4, Name=MTA')dnl yields a password dialog box from the client that isn't accepted by the service on the other end. Which is exactly why I've been chasing my tail as I have.
You should be fine with DAEMON_OPTIONS commented (just insert dnl at the beggining of the line). Unless of course you know what you are doing, and you really want to limit sendmail to listen only on 192.168.0.4:25.
If you are getting password dialog box, and you haven't enabled user authentication in sendmail.mc, check you mail client settings. Make sure "server requires username and password" is not set. User authentication section in stock Fedora sendmail.mc is not enabled by default.
If you do want to have user authentication, check if you uncommented all required lines for it in stock sendmail.mc (commented by default), and that everything is the way it should be. Not sure if you'd also need saslauthd running (check what you have in /usr/lib/sasl2/Sendmail.conf). If you do, check if you configured saslauthd correctly (/etc/sysconfig/saslauthd), and if it is running or not.
Also note that (if you enable default auth config in sendmail.mc), plain/login is allowed only over TLS. Make sure "use SSL/TLS" check box is also checked in your mail client in this case (or allow plain/login on cleartext link in sendmail.mc).
