That is no qualified entry.

You will have to setup your Fedora host on which Sendmail is running
with a FQDN (fully qualified domain name). For internal / home use it is
sufficient to have something like

192.168.0.50     fedora3.invalid   fedora3

in your /etc/hosts file. No changes in sendmail.mc needed for that. You
can run

/usr/lib/sendmail -bt -d0.9 < /dev/null

to see what your Sendmail config says about itself.
