I have an issue with my VPS and Mails on OVH.

I ordered a VPS and domain name for it. In Cpanel, I created a new user, added my domain name and some emails account. Website works fine and the same for mails (Can send et receive emails). My only issue with emails is Spam Assasin. All mails sended from my domain name goes to spam folder everywhere (Hotmail, Gmail etc).

This is “error” message:

0.0 CK_HELO_DYNAMIC_SPLIT_IP Relay HELO’d using suspicious hostname* (Split IP)

I don’t know if i configurated correctly my DNS.

This is my configuration:

NS: dns16.ovh.net.
NS: ns16.ovh.net.
MX: vpsXXXX.ovh.net
A: My VPS IP
AAAA: My VPS IPV6
SPF: "v=spf1 a mx mx:vpsXXXXX.ovh.net ip4:51.XXX.XXX.XXX ip6:XXXXX:XXX:XXXX:XXXX:0:0:0:53ca ~all"
DMKEY: v=DKIM1;k=rsa;p=[My Key];
