That's kind of odd unless someone had changed sendmail.  The default
setup on RedHat/Fedora for a long time has been that sendmail will
not accept mail over the network unless you make a change and
rebuild sendmail.cf.  Had the machine been kept current with
updates while exposed to the internet?   Unless you know who
made that change, I'd consider a complete re-install at the
first opportunity.
