I just noticed how to set up the DNS record for the Email server on Cloudflare DNS.

It should be DNS only.

I have my very own Email server, with IP address, a.b.c.d. It is powered by iRedmail.

In Cloudflare DNS. I should set it up like this.

1) Add an A record for this mail subdomain.

Type Name IPv4 address Proxy status
A mail a.b.c.d DNS only

2) Add an MX record that points to the subdomain above.

Type Name Mail server TTL
MX @ mail.example.com Auto

I was doing it in the wrong way. Made it in Proxied.

Then no email can be sent and received.  When I use Thunderbird Email App to retrieve the emails, it shew TimeOut.
