Sentora and 1and1: Problems with DNS MX records, why mail is not coming?

Question

Domain Name System

I have a VDS server with Sentora on CentOS 6 and a domain (say mydomain.com) purchased from 1and1.

Here are the settings I made in the 1and1 web interface:

Name Server Settings 
    	Name servers: 
    	(*) 1&1 name servers
        ( ) Other name servers
    
    A/AAAA and CNAME Records 
    	IP address (A Record):
    	( ) 1&1 IP address
    	(*) Other IP address
    	IPv4 Address 111.222.33.44
    	IPv6 Address (empty)
    
    MX Records 
    	Mail Exchanger (MX Record):
    	( ) 1&1 mail server
    	(*) Other mail server
    	MX1  mail.mydomain.com	Priority 10
    	MX2 
    	MX3 
    	MX4 
    
    TXT and SRV Records 
    	(none)

In Sentor, I made a mailbox [email protected]
Sent an email from my other mailbox [email protected] to [email protected], it did not come, and even the chipper did not come.
Conversely, emails from [email protected] to [email protected] also do not silently arrive.

Also, even though I see target mail.mydomain.com in Domain Management / DNS Manager, mail.mydomain.com does not resolve.

What did I do wrong and how to fix it?

Answer 1

does the server host respond contains a domain entry?

Answer 2

Create a mail record and direct it to your server
