I have been using Cloudflare for a month. Cloudflare SSL was turned on in Full mode.
My domain mail was not proxied by Cloudflare, so it worked, as I understand, under my old Let’s Encrypt SSL certificate that was installed by my hosting provider before I switched to Cloudflare. Today that LE certificate expired, and the mail become inaccessible through POP/SMTP (webmail works).
Hosting support said that they cannot install new LE certificate for me as I handed over DNS management to Cloudflare. So, should I remove my website from Cloudflare temporarily to install new SSL certificate or there is another way to repair the access to mail?
