Go to www.sendmail.org. There is a spam section on that page. pick up
the Check_rcpt and Check_relay rules. They work on the domain level, but
are very nice. There is also some stuff to do host banning and blacklist
banning as well. I run the stuff here. Only get like one or two a day at
most (usually a couple a month). Let me know if you need help. Thanks.

How can I prevent my host/machine being used as a stepping stone to relay

I am running sendmail 8.8.8
Sorry for the naive, possibly FAQ.
