The only one tip I have right now is that the reverse DNS query of the server's resolves to a different host than the one sent in EHLO, but in that case I don't know how to avoid that since the hosting where the dedicated server is located automatically assigns their own host to each IP. Could this have something to do with it?
get fcRDNS ...OVH lets you set a correct rdns for you hostname.
