Feature Request : support for disposable emails

[Aarbel]

Do you plan to add an option for isEmail() to forbid disposable domains ?
Thanks a lot !

I don't think it's a good idea to add these kind of validators to the library since we're never going to be able to actually stop all disposable emails and most people who's going to use it wont understand that.

As an option could be great !

@linkinmedo of course, someone that is really determined will always be able to bypass a check like this. But, for the most part, I'd say people wanting to create a fake email address will google "temporary email address" and use something from the first few results, which I am sure will be easily detected by lists such as https://github.com/martenson/disposable-email-domains/blob/master/disposable_email_blocklist.conf

So with this in mind, I'd be happy to make this PR, it sounds fun 😄

go for it ;)

We don't want to use an external list for this, and if we would provide our own list it would not be updated enough. You can provide the list linked above in the host_blacklist option to achieve the same result.
