Lots of info now, but I still can't spot the problem. Perhaps someone better versed in mail transport issues, than I am, will.
Is there a local user called "Ocean"? There seem to be a lot of complaints about that. If so, is "Ocean" forwarded to "
rlaxxx@free.fr" in /etc/aliases, and have you run "newaliases"? What does "host free.fr" return?
