Warning - Reverse DNS does not match SMTP Banner

[EN1GMA]

Hello,
Maybe someone can help me... Im in 3 days with this and cant handle It anymore!

I have one dedicated server on OVH and I have two nameservers setup?
ns1.enigmahost.org
ns2.enigmahost.org

With the IPs:
ns1.enigmahost.org
46.105.121.215

and

ns2.enigmahost.org
94.23.78.68

All my websites, after a whois, appears with the same IP:
46.105.121.215

This is how I have my domains setup:

Now I want to launch two new website:
domain1 with the IP 94.23.78.68
domain2 with a new IP that I buy yesterday: 178.32.52.69

Everything is working fine, all my website still have the main IP 46.105.121.215
And domain1 have the IP 94.23.78.68 and domain2 have the IP 178.32.52.69

The problem is that after I check in MX Lookup Tool to see my IPs, in both of them appears the same error: Warning - Reverse DNS does not match SMTP Banner

And I don't know how to solve It.

Ths both IPs are also listed on D.D.N.S.B.L (v4bl.org), I tried to removed but they was denied, could be because of the Reverse DNS does not match SMTP Banner?

They said: Before complaining please take note of the text to the right of the IP, as it may indicate the denial reason. Also, as it appears that most denials are related to improper FCrDNS, please familiarize yourself with the FCrDNS process/requirements before continuing with your removal request(s)
(and read through this link which shows some typical reasons why we list IPs):

Please help... I'm desperate!

Best regards,
Tim
