It should almost work out of the box.  Fedora ships an intentionally 
broken sendmail configuration that won't accept mail from anything but 
the local box.  To fix it you should:
yum install sendmail-cf
Then edit /etc/mail/sendmail.mc and remove the Addr=127.0.0.1 
restriction from the DAEMON_OPTIONS line and restart sendmail.

If your program involves an alias or forward entry that does a 
pipe-to-program, you need to put the program or a symlink to it in 
/etc/smrsh because sendmail is configured to ignore any path and only 
execute files located in /etc/smrsh/.

Once you get the basics working you should be able to diagnose any other 
problems from the log messages in /var/log/maillog.
