According to MultiRBL.valli.org - Results of the query 91.203.213.91 the IP of your domain is only listed in one obscure banlist. Who generates the message?

This IP: 82.135.102.232

You can test it yourself on multirbl.valli.org, e.g. MultiRBL.valli.org - Results of the query 82.135.102.232
I don't see big issues there. Maybe the cause is something different? Did you update your SPF record at your data center so that it reverse-resolves your new IP to your mailserver's hostname? It would still be interesting to know where the rejection warning message originates.

Yes, The rdns point From new IP to the DNS. But what do you mean with SPF on datacenter?
