Yesterday I updated Linux to the latest version (CentOS Linux 7.7.1908) and I noticed that I did not receive any e-mails.

Is your problem recovering?

krystian_rzepa

aaPanel_Jose
Yes, the problem persists. I reinstalled MailServer, but it didn't help.

I get this error some time after sending an email:
DNS Error: 12857270 DNS type 'mx' lookup of krystianrzepa.pl responded with code NOERROR 12857270 DNS type 'aaaa' lookup of mx.krystianrzepa.pl. responded with code NXDOMAIN 12857270 DNS type 'a' lookup of mx.krystianrzepa.pl. responded with code NXDOMAIN

This error indicates that your domain name is not resolved.

aaPanel_Jose
So what can I do with it?

aaPanel_Jose

krystian_rzepa
Resolve an A record to your dns console mx.krystianrzepa.pl

krystian_rzepa

aaPanel_Jose
I have all records

aaPanel_Jose

krystian_rzepa
I can't check your A record just before you reply.
Now I can check your A record, please try to send a mail test.

krystian_rzepa

aaPanel_Jose
I still can't see the emails.

krystian_rzepa
Check the log of the mail server to see if there is an error?

Has been fixed, I found that your ports 25,465,587,110,143,993 have not been released, but the panel display has been released, this may be caused by upgrading linux
I re-released these ports in the panel and it worked
