What is the issue you’re encountering

I have an email server (with Mailu) with a Roundcube client, IMAP, SMTP… and I would like to host it through Cloudflare while still having the A / AAAA and CNAME records for the webmail to have the proxy feature enabled

What steps have you taken to resolve the issue?

I tried to point the MX record to the CNAME of the webmail, but it does not work. If I understood correctly, Cloudflare proxy servers only expose port 443 and not other ports like 25, 587, 465… that I would need to be proxied to my server. Is that right ? Is there a workaround ? Is there a way to use Cloudflare proxy feature and host an email server ?
Thanks in advance for any answer

What feature, service or problem is this related to?

DNS records

Cloudflare only proxies HTTP/S unless using Cloudflare Spectrum. Spectrum is an add-on that requires an Enterprise plan to proxy any TCP/UDP port…

Thanks for the quick answer, exactly what I needed.
I will not pay for this feature, so I have no other choice but to create secondary A and AAAA records for email, that are not proxied. I will keep the webmail proxied, however.
