We host a number of LISTSERV Lists for our customers. We participate in AOL's Feedback Loop. AOL forwards copies of emails that its customers have indicated are spam (by clicking the Report Spam button) that are sent from our IP. This is all well and good, except AOL strips the recipient's email address out of the email's headers. Therefore, you have no idea who is clicking the Report Spam button in order to remove them from a list. When we receive complaints about lists, we require our customers to validate their subscriber lists by removing all AOL customers and asking them to resubscribe. No other method (such as emailing the AOL subscribers about the problem) has been effective. Of course, our customers are very unhappy about this. Most swear their lists are opt-in only (which generally is true) and are demanding we find out who the complainers are. To this end, we have contacted IMail to try to get some assistance with this. Today, we finally got through to someone at Tier 2 Support, who made this recommendation: "Script all messages to AOL list members with a unique identifier to be able to identify who is reporting the spam. This identifier needs to be inserted into the header in such a way as it is not stripped by their TOS Client reporting stuff." Of course, they gave us no documentation nor information about what would/would not be stripped out of the header by their TOS notification software. Nor did they provide any code or other instructions. We are left to try to figure this out on our own. If anyone on the list has ever done this and can provide us with code and instructions, it would be greatly appreciated. Thank you.
