I recently purchased VPS service to allow me to host a site. My mail provider is zoho.com. In order to get it to work, I would need to add 3 entries under Mail Exchange records (MX Record) as the following page instruct https://www.zoho.com/mail/help/adminconsole/configure-email-delivery.html
I enabled SMTP service following the instruction listed here https://www.znetlive.com/blog/how-to-configure-smtp-server-in-windows-server-2016/
Then I opened port 25.
Then I went under "DNS Manager" and added the following info
But still can't get it to work. Zoho mail can't see the MX records. I tried to check the status of the mail setup https://mxtoolbox.com/domain/realestatebyareen.com/
But that is given me errors.
How can I fix this issue and correctly setup SMTP and add the MX records?
