It seems the spammers like to target secondary mx machines and let those machines relay the email to the primary machine. I've tried setting up the virtusertable file to at least reject invalid emails on the secondary mx machine, but it seems that sendmail bypasses that when it's doing mx relaying for that domain. So, does anyone have some suggestions to partially lock down mx relay machines?
