I have a DA server where I host domains and mail. Now I want to seperate mail and domains one by one.
I setup a new server with Directadmin and synced everything and want to use this as mail server only.
So currently I have
Old server (which needs to be online till the last domain is migrated)
New server 1 with DirectAdmin for mail only
New server 2 only host domains
The problem is when I migrate one domain with email and point DNS to the servers as above, then the mail does not work correctly.
When sending a mail with mailsoftware it works and test with mail.tester.com score...
