Hi,
It might be possible that the destination server is rejecting your emails based on the DNS records not being published for the email address used to send emails.
You can check the DNS records.
If the DNS records are fine then you would need to check with the destination domain to know the criteria they are using for your domain.
Thanks

thanks for your reply. When i check dns issue using mxtoolbox is seems it is ok.
what the interesting part is that i didn't do anything but email reaches to destination properly. i didn't understand that where was the problem.

This usually occurs because of some restrictions at the destination server.
If possible reach out to destination server to find why they are rejecting your emails.
