ok i missed some thing

RFC 1912                   Common DNS Errors               February 1996


    Make sure your PTR and A records match.  For every IP address, there
    should be a matching PTR record in the in-addr.arpa domain.  If a
    host is multi-homed, (more than one IP address) make sure that all IP
    addresses have a corresponding PTR record (not just the first one).
    Failure to have matching PTR and A records can cause loss of Internet
    services similar to not being registered in the DNS at all.  Also,
    PTR records must point back to a valid A record, not a alias defined
    by a CNAME.  It is highly recommended that you use some software
    which automates this checking, or generate your DNS data from a
    database which automatically creates consistent data.

So your are right and i'have to phone to our isp....
