You should have to change:
DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')dnl
in sendmail.mc then rebuild sendmail.cf and restart sendmail, and
add your network address to a line in /etc/mail/access
192.168.0 RELAY
for networks that should be able to forward non-local mail
out through this server, then rebuild the access.db database.
Most (all?) fedora versions will do the rebuild if you type
'make' in the /etc/mail directory.
If you are running iptables firewalling, you'll have to allow
port 25 in.   You can test whether you are permitting connections
by trying to telnet to port 25 from another machine:
telnet yourserver 25
You should get a greeting from sendmail - exit by typing 'quit'.
If you get that far, any client rejections should result in a
log entry in /var/log/maillog with the reason.  If you still have
problems, please post one of these log entries.
