Well, if your server is 'ns507557', it clearly tried to deliver an email via smtp to mxttn.le-pic.org[89.234.156.206] and was greylisted.
oh... I guess than postfix tried to send back something to test-owner
Probably an NDR - a non-delivery report. I don't know how well you know Postfix, but at the time you got the greylisting, the mail would still have been in the queue - show the queue 'postqueue -p' show a mail from the queue - 'postcat -q <id>' -- Per Jessen, Zürich (3.6°C)
