That's the thing. I DO VERP our SMTP envelopes, but Comcast's FBL reports only include this:

User-Agent: ReturnPathFBL/1.0
Abuse-Type: complaint
Arrival-Date: Wed, 29 Jun 2016 15:23:37 +0000
Feedback-Type: abuse
Version: 1
Source-IP: 207.154.13.48
Original-Rcpt-To:8d29aa11b1810bec67beca0de3554...@lists.fusn.org
Original-Mail-From:fusn-ow...@lists.fusn.org
Reported-Domain: lists.fusn.org


ForwardedMessage.eml

Subject:
[8d29aa11b1810bec67beca0de3554359] Free: pair of planters
From:
<redacted by me>
Date:
6/29/16, 11:23 AM

To:
8d29aa11b1810bec67beca0de3554...@lists.fusn.org


Note that the

Original-Rcpt-To:8d29aa11b1810bec67beca0de3554...@lists.fusn.org

and
To:
8d29aa11b1810bec67beca0de3554...@lists.fusn.org

Addresses are not the VERPed address, or even the recipient address. They seem to be an obfuscated version of the LIST address. Not really helpful.

As far as I can tell, there is NOTHING in the abuse report that can be associated with either the final recipient or a message-id that would let me locate the message in our outgoing logs (from which, given VERP, I could find the recipient).

Based on other comments, I sent a query to Return Path - I'm half expecting that they'll offer to sell me the info, or a slot on their whitelist.

Sigh...

If you VERP the SMTP envelope sender address, that should help you out. It comes back embedded in the report as "Original-Mail-From:"
