I'd be curious to know what this checker says about the IP address that ultimately got this ISPs attention: http://mxtoolbox.com/blacklists.aspx

I run 2 fast exits with only ports 25 and 465 rejected. I find that the IPs are in some expected lists that target Tor, plus barracuda and spamhaus-zen. But not a gigantic pile of RBLs like was being described. No sorbs, no spamcop, no uceprotect. Nothing like a real spamming box.

Doing nothing on email ports but still ending up on a meaningful number of RBLs doesn't sound right. Maybe all it took to piss the ISP off was for one of them to do it.
