If that's all, and there's no logging from postfix/qmgr or any indication that the message was quarantined, and no evidence of the queue-id in "mailq" output, then the message was simply never received in full, because the sender aborted transmission before ".". There's likely a relevant "postfix/smtpd[762503]" disconnect log entry that evidences this. The verbose logging is definitely not helpful, without it, the collate Perl script should show a concise picture of the history of this partially received message: https://github.com/vdukhovni/postfix/tree/master/postfix/auxiliary/collate -- Viktor.
