Cannot send e-mail to another server

[inomi13]

I can't send e-mail from my server to some server because I have received below information. I checked in another server and there is works. Where should I look for the problem ?

directadmin 1.654
httpd 2.4.58
dovecot 2.3.21
exim 4.96.2
pure-ftpd 1.0.51
mysqld 10.5.22
named 9.11.4

all relevant MX records point to non-existent hosts

all relevant MX records point to non-existent hosts

Is this the info you got? If yes, seems your domain is not resolving or you did not configure any MX records, or if you are using external DNS, you did not copy the records to your external DNS.

Hard to be of help without further information or domain name.

Check your Exim logs.

Also visit https://www.mail-tester.com and follow the procedure, if mail is send you will get a score there, everything which is lower than 10/10 will explain what you have to do to improve.

In my server I have more than 100 domains and I can't send e-mail any to only one domain. I'm sending email to others servers (Microsoft, Google etc.) and all are delivered so why record MX in zone DNS is would be incorrect ?

In exim log I didn't find any sugestion where is the issue.

Sorry, misunderstanding. I thought with "some server" you ment a couple of server.

In that case, especially if you don't have issues sending to Google and Microsoft etc. it looks an issue somewhere else.
You can always see if you get a 10/10 score with mail-tester too just to be sure.

However, their DNS records look correctly too.

What do your Exim logs say if you try to send to psgaz.pl domain?
Does the issue occur when sending from a specific domain from your server or from multiple domains?

I don't know where was an issue but I restart exim and after that I can be able to send email to this domain.
