Hi, I am about to setup an email server. Is Cloudflare, strong passes and updated softwares, ssl enough to protect me when the ports are open for the server?
Cloudflare doesn't proxy email (except for specialized products like Area1 or Email Routing), so it will be entirely up to what/any software you're running on the email server itself.
probably, cloudflare was even using google trust services for quite a while before google made the service publicly available so it wouldnt surprise me theyd get access to ecdsa early as well
