You should not have drawn the red line because that will point you to the issue.
The host or domain name can not be found it says.
Sorry, can't help if we can't investigate what is going wrong or why it says domain does not exists.M7Web said:Plus the domain and email exist.

Indeed try with intodns.com or dnsstuff.com to check things.

It seem your client is connecting to mailserver ovre IPv6 (which looks to be enabled in DA) but the AAAA (IPv6 A record) appears to be missing for the domain tavipapelaria.com.br
The by DA generated SPF records are normally correct, so no need to remove them, just let them in there.
DNS looks fine in all queries I've done until now. the only thing is that there are cnames used.
Also it looks like you do not have a proper rDNS for your mailserver, but that should not stop anybody visiting the domain name.
So try this, first tip of Remitur. Create an A record for tavipapelaria.com.br without the www, so only domain name, otherwise you will keep having issues.
Remove the www CNAME and create an A record for that too, makes things quicker.
Then create the correct rDNS for 142.44.188.79 to srvda1.serverdns.srv.br to have your mailserver correctly setup.
This kind of misleading message does appear often when the issue is not about AAAA, but about DNS consistency; I guess that it's caused by AAAA being the last (failed) check done before giving up, but the real meaning is "somereason I can't resolve the email server"
How can I disable AAA IPV6?
I do not use IPV6 on the server.
I see that domain is not giving DNS issues anymore... but also that you edited SPF record (which is different from yesterday).
If you did not edited other records, I guess that it was (as I suggested) some kind of error in previous SPF record version.
That depends, if they all use their own helo from the mailserver, then yes you have to.I changed rDNS to the server hostname, do I need to do this for all IPs on this server? 1 IP for each resale.
Ofcourse you can, inspite of the fact what Remigur says. We have visitors on the forums on our servers with ipv6 adresses and we only use ipv4 on the servers.How can I disable AAA IPV6?

It's better not to remove them, however if your mailserver uses them, you have to use an rDNS for ipv6 too.
We don't use ipv6 on our servers. It's easy to disable, depending on the distro you're having.
That is correct, which it also said in my expanation where it states we only use ipv4 on the server.Remitur said:What you say, is instead disabling IPV6 accessibility to your own server, which is a totally different matter.
