A probe relies on the bouncing mail server to bounce to the correct address (RFC821 MAIL FROM) whereas these "reflected" e-mails are a case of a very broken mailer bouncing mail back to the list address (which means it's using the To:, Sender:, or possibly Reply-To: address -- whichever it is, it's the wrong thing to do and the probe won't catch it :-( ). Jacob, you need to follow the headers and determine at which point it started heading back to the list. Then do a scan on your list for that domain, and delete whoever you find with an address there. If no one is there, it may be that another address is forwarded and so you need to back up a bit in the received headers to find the subscribed address. If you're not sure which address is the culprit, you can temporarily set your suspects to FULL822, so that the headers can tell you exactly which address it is. Francoise
