It's not all places using the filter. As for how smarthost affects 
sendmail I can't say (using postfix) but I think it shouldn't affect the 
incoming mail. More plausible reason for incoming mail now working is 
that you restarted the sendmail when changing the configuration and that 
made it work. But if I were you I would follow it for a while to see how 
the things go and keep track if you get bounce messages for the e-mails 
you send.

In any case upgrade your server to more recent fedora 10-11 or if you 
don't feel upgrading the server once a year I would recommend changing 
to CentOS. In any case running old Fedora open to internet is just 
invitation to get hacked.
