From RH 7.3 to FC 1 the Sendmail version changed from major version 8.11
to 8.12 which implicates a major layout change within Sendmail.

That is good, because needed. For security reasons this restriction to
localhost is default.

Better erase that line and exchange it with
192.168 RELAY

No restart needed! If you modify .db files like access/access.db just
run afterwards "make -C /etc/mail". Changes will take place immediately.

Ok.

This should be better investigated.

Looks ok.
Check that you have following line in /etc/hosts:
127.0.0.1 localhost.localdomain localhost
Also check the output of "sendmail -bt -d0.12 < /dev/null".
If you like (and do not post the info to the whole list) you can
privately mail me your mailserver IP address / hostname and the output
of the command above. You might also increase the loglevel for Sendmail
with following line in sendmail.mc:
define(`confLOG_LEVEL', `15')dnl
This will result and a more verbose output to /var/log/maillog.
