Trouble with receiving mail

[orzklv]

After the last discussion, I got my mail ports opened and mails server seemed to be working as I could send mails from the server. However, later I found out that I'm having issues with receiving mail. First, I started sending mail to primary domain [kolyma.uz] and icloud server showed that mail was sent and inbox of email server was empty. Then I tried to target mail domain directly [mail.kolyma.uz] and this time got error from icloud itself:

Please authors, forgive my stupidity. It's just i'm learning and wanted to start with this mail server project. Maybe this discussion may serve for better in the future for other beginners 🥹

Ok, needed to set up one more MX record with priority 1 to @ of domain appointing mail sub domain.

@ MX mail.kolyma.uz 1
