Somehow, we're on some spam software's list of open relays, I think. We
aren't open to relaying, but people sure try. 

I'm guessing this is a bug in the software, but... when it can't relay, it
leaves the connection open, then goes and tries again, and again.....

I'll end up with hundreds of these sometimes.. They timeout in 15-20 mins,
but my server is thrashing so badly at that point, it's unusable.

Anyone see this? Anyone know what I can do?

Sendmail is almost always sitting in 'cmd read' or 'child wait'.
