Hy,
I have added Cloudflare to my site and after that I cant add my website email to my gmail for receiving emails. I can send emails as [email protected] from my gmail but when I add this email id to receive email it shows “Error connecting to mail address”.
I am using a shared hosting and here is list of dns records.
Cloudflare core service only protects websites (HTTP/HTTPS in particular).
But, you may take a look at Cloudflare Spectrum. It extends protection to almost any TCP/UDP applications. This includes protection of SMTP traffic, but more configuration is required. This is a paid add-on.
