I believe the ordb dnslists are not free anymore, but that is upto you to
go and find out. Perhaps you already did.
I use the following dnslists:

spamhaus.relays.osirusoft.com : spamsites.relays.osirusoft.com : \
dialups.relays.osirusoft.com : socks.relays.osirusoft.com : \
opm.blitzed.org : sbl.spamhaus.org : proxies.blackholes.easynet.nl

I use Exim, not Sendmail, so I do not know how to test, but suppose
you have a different box, you can temporarily assign the IP to it, then

telnet -s ip_of_sendmail_box 25

Then simulate a mail transaction and see what the sendmail says in the log...
