Which brings me back to my initial question - anybody from Comcast here, or can somebody point me at an appropriate contact at Comcast?

(of course this may be Return Path pointing a finger)

Thanks,

Miles

Note the quote from the Comcast FAQ page "The ISP may redact..."

That seems to indicate that this is Comcast's decision, not Return Path's.

    Well, I just received this from Return Path:

    -------

    Thank you for contacting us.

    In order to obtain more information about the abusive user, you
    may implement a tracking ID, Please see the information below
    that is provided in  the Comcast FAQ page:

    "The ISP may redact parts of the original message to protect the
    privacy of their users. In the event an ISP redacts subscriber
    email addresses from their feedback loop messages, you should
    incorporate a tracking ID unique to the recipient's record in your
    database and your messages so that you can process the removals.
    You can add this ID in the body of the message or add an "X"
    header in the header of the message. An example of this could be
    "X-SenderName-ClientID: 543432".

    --------

    I find it rather disturbing that one of the major vendors of spam
    filtering services does things in such a non-standards-compliant
    way.  Everyone else (well, AOL, Yahoo, the other "big boys") seem
    to return message-id along with an FBL notice.  Return Path seems
    to filter it out.

    That's just painful.

    Sigh.

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

    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...

        Is there anybody here from Comcast mail operations who can
        provide some guidance as to how to identify the originator
        of an abuse report, so I can remove them from the list(s)?


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