My emails to hotmail and outlook goes to spam i have this:
(If i send to gmail its fine)

mail-test.com 9.7/10
Your Reverse IP doesnt match with your hostname:

Your IP address its associated with the domain 140.ip-51.253.22.eu.

But you email seems to be sent by hostname vps.jsjsjd.ovh.net

IP: 51.254.33.160
HELO: vps.jsjsjd.ovh.net
rDNS: 140.ip-51.253.22.eu
If i change /etc/hostname from vps.jsjsjd.ovh.net to 140.ip-51.253.22.eu then mail-test.com 5.3/10

Your IP address its associated with the domain 140.ip-51.253.22.eu successfully

IP: 51.254.33.160
HELO: 140.ip-51.253.22.eu
rDNS: 140.ip-51.253.22.eu
Oh! and if i put "nslookup MYIP" in centos7
Server: 223.146.33.19
Address: 223.146.33.19#53

Non-authoritative answer:
140.22.253.51.in-addr.arpa name = 140.ip-51.253.22.eu.

So what can i do? THX!

Try to add dmarc record and read filtered email headers. Maybe headers will be some useful info.
