Legitimate list-management systems allow users to change their email address, but only after verification from the new email. So, from web site: user requests change, email sent to new address with confirmation code/id, new email replies through web or email - modification then takes place. The biggest place for bulk email abuse is transferring old lists to a new provider. The new provider needs to allow the old list of names to be mass-uploaded. For this process to be invisible - one needs to trust the upload as legitimately captured email addresses. Even sending new confirmations to the uploaded list may result in x2 spam if the uploaded list was spam to begin with. To counter this, the uploaded list needs to be scanned first for "spam like email". If they occur, upload of the list is prevented, the list is stored temporarily, the list owner is flagged, the uploading individual is flagged, and only after manual examination and conversation between the uploader and list provider is the upload allowed (if approved). And still it's not foolproof. Stephen R. Cassady http://www.tallylist.com List Management, Archiving, and Analysis <-- Message Reply To --> Well that is the way that I subscribed to this list so maybe that is what I saw, but as most mail clients allow users to change their from addresses to anything they want - you can subscribe anybody via a mail client with very little effort ( or make a program that could subscribe people in bulk without their knowledge -- and without any validity check on the address). I find this lack of security/privacy feature in the list server of this well regarded mail server somewhat shocking. It must leave lists on its list server open to abuse and spamming and must be a hole for DoS attacks on the mail server.
