Thanks Jeff,
I hope others will post on their experience as well. Below is the contents of the details.txt file returned from another ISP.
Some things to note:
1) I have never sent a complaint to this ISP until yesterday.
2) I sent the complaint to three of the addresses uncovered by SpamXII.
3) None of the addresses that refused delivery is among those to whom I sent a complaint.
4) What follows is copied and pasted as-is from the details.txt file except that I munged my e-mail address.
