Greylisting is a matter for the receiving server, not for the sending. If this is your server being greylisted by mxttn.le-pic.org[89.234.156.206], there is probably little you can do, but at least start by making sure your IP addresses are properly reverse mapped in DNS.
I know very well the le-pic.org admins, and will see this with them but how can this be when I only receive the message?
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. Most greylisting is done for all hosts, very few exceptions, and the sending server only has to retry after the usual interval, typically 15minutes. -- Per Jessen, Zürich (2.4°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland.
