The thing is as follows: You sent an email to the list. The list server sent it to the thousand (?) subscribers. One of them has been marked as a spammer by his ISP -- Good job! Praise them! :-) --, and his account was blocked. That ISP sends back a notification to the originator of the email, which is you: at least, you are in the "from" header. maybe it should have bounced to the list server: Christopher could perhaps clarify that, I think.
Bounces and autoresponses (e.g., vacation messages) should only go to the sender from, not addresses listed in the from or cc header. When that happens the person will eventually get automatically unsubscribed and no one ever sees this garbage. -- -ckm
