How to block Disposable Email Addresses in your website's registration form? [closed]

This is tough, because neither whitelisting nor blacklisting are an option.

By whitelisting certain domains, you disallow people with email domains that are unknown to you (but might be perfectly valid), while by blacklisting you have to update the list of blacklisted domains on a daily basis, since new "10 minute email" domains emerge every day.

Please note that temporary email addresses are invented for a way of saying: "Hey, I don't trust this website with my own email adrress", so you're most probably not going to trick users that are willing to hide their real address since they've got a valid reason to do so.

Can't you adopt and implement something like OpenID?

I'm facing the same problems so I create a Free API service that recognize disposable and temporary email address: Block Temporary Email

Email Endpoint:

GET https://block-temporary-email.com/check/email/example@simplemail.top

JSON response:

{  "status": 200,  "domain": "simplemail.top",  "temporary": true,  "dns": true,}

This API is free for fair use, but do you need an API Key making the register for free.

Disclaimer: I made this API

Yet another list of DEA domains, built by merging the lists I could find on the web (in 2015):
