Sending but not receiving mails(centOs, postfix) - Probably dns issue

Question

The error message:

Delivery to the following recipient has been delayed:

 contato@domain.com

Message will be retried for 1 more day(s)

Technical details of temporary failure:
DNS Error: 353969976 DNS type 'mx' lookup of domain.com responded with code NOERROR
353969976 DNS type 'aaaa' lookup of mail.domain.com.domain.com.br. responded with code NXDOMAIN
353969976 DNS type 'a' lookup of mail.domain.com.domain.com. responded with code NXDOMAIN

This is my dns zone(db.domain.com.conf):

;
; BIND data file for domain.com
;
$TTL    3h
@   IN  SOA     ns1.domain.com. admin.domain.com. (

@c4f4t0r he already has it. OP, what does `nslookup -q=mx domain.com` return? — sysfiend, Jan 09 '17 at 16:49
[root@vps0818 ~]# nslookup -q=mx domain.com Server: 186.202.26.26 Address: 186.202.26.26#53 Non-authoritative answer: domain.com mail exchanger = 10 mail.domain.com.domain.com. Authoritative answers can be found from: [root@vps0818 ~]# — Éder Rocha Bezerra, Jan 09 '17 at 17:00
If the file is just how it looks like in your post, just change the serial number, save and restart. If it works, I'll elaborate an answer :) — sysfiend, Jan 09 '17 at 17:07
@Alex I don't know what serial number you're talking about. Can you be more directly? — Éder Rocha Bezerra, Jan 09 '17 at 22:46
@ÉderRochaBezerra in your DNS config file it says "Serial" and there's a "1" on the same line. Change that number, save and restart/reload — sysfiend, Jan 10 '17 at 09:11
@ÉderRochaBezerra try executing the command I mentioned before but ask a different DNS server for the answer (one that, for sure, didn't answered before), you can do that by adding the IP of another server at the end of the command. Also, DNS changes take time to actually be effective. — sysfiend, Jan 10 '17 at 18:08
@SysFiend `[root@vps0818 ~]# nslookup -q=mx microsoft.com Server: 186.202.26.26 Address: 186.202.26.26#53 Non-authoritative answer: microsoft.com mail exchanger = 10 microsoft-com.mail.protection.outlook.com. Authoritative answers can be found from: [root@vps0818 ~]# ` — Éder Rocha Bezerra, Jan 13 '17 at 15:33
@ÉderRochaBezerra not like that, you need to execute `nslookup -q=mx domain.com 8.8.8.8` being 8.8.8.8 a nameserver. — sysfiend, Jan 13 '17 at 15:51
