Issue with mails - DNS & VPS

Hello,

I have an issue with my VPS and Mails.

I ordered a VPS and domain name for it. In Cpanel, I created a new user, added my domain name and some users emails. 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];
