I wouldn't suspect any relaying currently happening, especially if you've upgraded to sendmail 8.9.x and (presumably) updated your sendmail.cf file. You're probably experiencing the backlash from the initial relaying in the form of bouncing messages, refused messages, etc. The large-scale relay abuses that I've witnessed have almost always seemed to generate significant machine loads in the resulting aftermath. I don't know if this is characteristic or not, but the quality of some spammer address lists seems to be about 50% bad addresses (or worse). You may have to turn off sendmail (if possible) for a while until the backlash blows over.
