mx shows ip

hi there ,

i've put my domain - server behind cloudflare .
the server has an MX - mail service aswell .
i created a mail subdomain pointing to my server ip.

and created an mx pointing to mail.dom...

however when checking my mx to see if its protected , all services like https://dnschecker.org/mx-lookup.php?query=

will show my server ip .

what can i do to fix that , thank you

According to the Cloudflare documentation, this issue is related to the dc-#####dc-##### subdomain that Cloudflare creates to overcome conflicts with MXMX or

SRV

SRV

records.

As stated in the documentation (https://developers.cloudflare.com/dns/troubleshooting/email-issues/), "The dc-#####dc-##### record ensures that traffic for your MXMX or

SRV

SRV

record is not proxied (it directly resolves to your origin IP) while the Cloudflare proxy works for all other traffic."

To fix this issue, you can update your MXMX record to resolve to a separate

record for a mail subdomain that is not proxied by Cloudflare.

Here's an example from the documentation:

example.com MX mail.example.comexample.com MX mail.example.com
mail.example.com A 192.0.2.1mail.example.com A 192.0.2.1
example.com A 203.0.113.1example.com A 203.0.113.1

By doing this, you will be able to keep your mail service protected behind Cloudflare while still allowing mail traffic to reach your server.

Please note that if your mail server resides on the same IP as your web server, your MXMX record will expose your origin IP address. It's recommended to use non-contiguous IPs from different IP ranges for your mail and web services.
