Hi everyone,

This is my first experience with IoNos Cloud (Centos7 OS)+WHM.

I have been trying since yesterday to install my mail server. so I currently have:

- a DNS configuration: Done.Figure 1

- a rDNS points to my domain host.Figure 2 and Figure 3

- and my WHM indicates that DKIM+SPF and PTR are VALID. Figure 4
(WHM root & CPANEL).

- Named. active ,confd and working. Figure 7

- Firewall open ports. Figure 8

but when sending emails I receive emails bouncing error 5.0.0 for certain destinations. Figure 5 Figure 6

for others I do not receive any acknowledgment message (Gmail.) Frozen

I really don't know what i m missing but If anyone could help me solve this problem I would be very grateful.


Thank you ALL.

Hey there! I'm not able to open your screenshot links. Can you try posting those here directly, or maybe using a site like Imgur to share those? If you could also share the full text of the bounceback message that would likely be enough for us to help.
