Email with external server 100% reject, need help

[TheNowus1]

Hello guys,

pls I need help.

We need to setup an external mailserver. So far so good, MX point right, DNS Table is setted wit DKIM DMARC and SPF, Also set to remote

But doesn´t matter what I do, not one mail go out. All come back with reject and add header. Seems the authentification is missing.
Honestly, I am new on cPanel and I don´t understand the matter, go crazy at time.

Every tut and shown ways I tried but it doesnt´help.

Can someone take a newbie at hand and do it? Because we don´t want to use the internal Mail System.

Thanks in advance

Michael

	Test	Result
	SMTP Reverse DNS Mismatch	Reverse DNS does not contain the hostname	More Info
	SMTP Banner Check	Reverse DNS does not match SMTP Banner	More Info
	SMTP TLS	Warning - Does not support TLS.	More Info

Think I killed it completely with the try to get back to internal mail service.
But now step by step.

WHM and OS:

• CENTOS 7.7 [green]

• v86.0.16

When I dig my host I get no IP, when I dig my domain I get IP.
So the message with my reverse seems right.

I use myLoc as hoster but I have no idea which DNS zone is right, I have one in myLoc management, than in WHM. The WHM have the A Record for Domain and Host, the myLoc have for domain......

When someone can help me trough this that I can use my own mailserver...pls let me know, little frustrated at time

Could you try to explain in more detail, without divulging email addresses etc.
