Greetings to all
I currently have a CentOS Linux 7.5.1804 server
Working with Plesk Onyx 17.8.11
I been working with Plesk for over 7 years but a year ago I had my server moved from an old server, running also Plesk, I used the Plesk migration tool to move all my domains
Today, all my domains stopped sending emails, from what I can tell, the domains migrated from my old server are working well, but all the domains installed after the migration in the new server and not working, the error message I get it says it has something to do with the DNS records.
I need someone to take a look at this issue, and help me fix it
