How to properly configure MX records?

I have currently just set up a server at home and installed Nethserver with the mail server package with roundcube. I have created the user and email account. I want to use nethserver as my email server to send and receive email.

I have port forwarded 465 for smtps and 25 for smtp.

Now a few questions below.

What do I put for the MX records for my domain DNS records? This part I have not done before and am confused what to put here. I have read up on what an MX record is but I am still unclear on what to put. I have a host section to fill out, then the IP address to point to my server location. The host section I am not sure what to put, is it the hostname of the nethserver, as in or something else?

Can someone give me an example. Anyone else have a home email server with a registered domain address.


Who is the dsn domain owner? Check it with
Find the owner and on dns configuration modify mx records filling out NethServer public IP (be static is mandatory)

Ok, my registered domain holder is and there’s whole a list of nameservers down the bottom of the listing. Here is a screenshot of my record options. Yes my ISP IP is static.

Create a cname like this <-> your.ip.static

Then into the MX configuration:
host = (empty)
Answer =

To find out more check also

@alefattorini maybe I’m mistaken but cname shouldn’t be used on an A record’s name?
I mean
A 123.234.432.321

Ok, I found some more information, apparently I am supposed to make an A record and leave the host section blank which will just have my domain name, and my external IP in the answer box. Then I am to create an MX record and put in the host section, and fill in in the answer section.

So yeah, I think the A record does the IP pointing, while MX just does the mail forwarding part only. Once I get a chance I will test this out, because it takes 1-4 hrs for my domain host to update these details. I will get back to you guys once I have tested it out and report back.

Thanks for the reply’s, I will try both of your ways out and see what happens.
