Can you explain how the backend works? Will it block Apple's 'hide my email' feature from functioning with valid @icloud.com addresses, or similar 'valid' domains with potentially disposable email addresses?

My team maintains a list of disposable domains actively, if the target domain couldn’t match existing records, we will verify its DNS record (coming soon) :PPP

(not OP) No, but you can block those with a regex pretty easily.

Developers and regex on email is always a terrible idea. So many fail to understand what the RFC allows (virtually anything). Can't tell you how often websites will reject an email address with a two-character localpart :-(
For such cases (refer to @icloud.com), no idea if we should take it so seriously…

For now, our goal is to detect disposable mails from online free providers.

Yeah I can relate to that... some don't even realize TLDs longer than 3 chars exist (my primary domain uses a 4 char TLD)
