Certain mailing list systems use a unique envelope sender for each recipient to track bounces. Is that the case here? When checking the headers of the bounce message, is the same domain of the sending relay in your logs for outgoing messages? If that is a low volume domain it might be possible to track it. -- Gruß Marco Send unsolicited bulk mail to [email protected]
