1. MX should be a CNAME to another domain not to the IP.

Example:

@ MX point to mail.domain.com
Then you create an A record mail pointing to the server IP.
You need to have 2 records setup CNAME + A so MX works.

If you wand to add pop.domain.com the easy way is another cname pointing to mail.domain.com.

2. If you use external dns you don't need to create ns1 & ns2 pointing to server IP as those DNS entries won't be used.

I don't get the point over server doors? You mean ports? DNS don't care about ports as long the DNS entry resolve correctly.

Hope it helps

Thanks for the friend, I'll do as you said I'll create the type A entry pointing mail.mydomain.com to the server ip, then I create two entries of the CNAME type pointing my.mydomain.com to mail.mydomain .com.br

About the doors ....
I asked why I have to free all ports on a firewall that stays before my server ...

I'm going to test the notes that you told me and then post here the result.

Thanks for the help, my friend.

I have created the following notes:

mail.mydomain.com A server ip
mx.mydomain.com CNAME mail.mydomain.com
pop.mydomain.com CNAME mail.mydomain.com
imap.mydomain.com CNAME mail.mydomain.com
smtp.mydomain.com CNAME mail.mydomain.com

Is correct?
