The reason you can’t receive email is because you’re using Cloudflare through the control panel. It’s a known issue with the Cloudflare integration in the control panel that it breaks a lot of other features.
The easiest fix is to just disable Cloudflare on the domain for now.

Oh, true ! thanks for this information well also i want to know if people able to ddos my website if i disable cloudflare ?
Well, people can launch a DDoS attack towards your website regardless of whether your use Cloudflare. Cloudflare can help reduce the effects of an attack, but nobody can truly stop a DDoS attack except for the attacker.
Besides, DDoS attacks are, generally speaking, a very small risk. How many times has your website received a DDoS attack so far?
