Yes, that does seem to be the case.

Nicolas, if you make the query directly from the nfrance.com servers
you can see what we mean:

    $ host -a microlinux.fr ns.nfrance.com
    Trying "microlinux.fr"
    Using domain server:
    Name: ns.nfrance.com
    Address: 80.247.224.77#53
    Aliases: 

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2088

    mx1.nfrance.com.    	    60    	    IN    	    A    	    80.247.229.29
    mx1.nfrance.com.    	    60    	    IN    	    A    	    80.247.228.29

So nfrance.com still claim SOA on your domain. At least they have a
relatively short TTL on it of 9600s so things will correct themselves
quite quickly once they drop the domain.
