I've seen this issue before: dspam sends a garbled RCPT (binary data, IIRC) when trying to deliver the quarantine message to postfix. Never found out why, I stopped using dspam quarantine (and used tag and deliver to spam folder). The original message as received by postfix has no problems. You could try to find the postfix logs for the incoming message by looking at the message id in the dspam quarantine, but the bug here is in dspam. -- Tom
