Relaying denied. IP name lookup failed [204.0.143.35]>

Any ideas??

Im not sure what the fix would be, but one possibility is
that the destination email server is doing a reverse DNS
lookup on your domain name and comparing that IP address
against the IP address of the server it is receiving the
email from and the two dont match. This is done to help
block spam.
