Presuming from your subject it's a RaQ4...

Under Site Settings for the site example.com there's a field "Email
Server Aliases".  If you do NOT put anything there, then sendmail will
accept email for www.example.com, but NOT for example.com.  So email for
someone@xxxxxxxxxxx will NOT be attempted for local delivery.

Don't forget to save any changes.

Under the Control Panel settings for sendmail you should also put
example.com into the "Relay for the following Hosts/Domains" window, and
save the changes.

This, and the DNS, should be all you need to do.  You might want to
verify that example.com, without the "www", doesn't appear in the
/etc/mail/local-host-names file, and that example.com DOES appear in the
/etc/mail/access file with RELAY after it.

It's pretty easy to set these up, even the reserved ones, on a RaQ4; you
just put them into the bottom of /etc/mail/virtusertable:

postmaster@xxxxxxxxxxx <tab> localusername
