That scenario is possible, but you may still need DNS MX records to point
to the smart host as well. You can have multiple MX records for a domain
(or subdomain) where the value field is higher for a farther away mail
server, or for a secondary mail server. Sendmail uses DNS to figure
routing along with the internal configuration file UNLESS you specify to
sendmail to NOT use DNS.
So you have some choices in how you configure sendmail and/or DNS.
Also it may help you to test things on one system and bump up the sendmail
logging so the /var/log/maillog file has more information. Use the option:
-O LogLevel=80
Or some other value than 80. You can add these options to your sendmail
flags in /etc/rc.conf
