misc.is_disposable is always false for disposable email addresses

disposable email providers like inboxes.com

What happened?

The docs for mailchecker:is_valid() state:

The mailchecker crate provides a is_valid(email) function that ensure the email is valid and does not come from a disposable email service.

This means that email addresses from disposable email providers fail the initial syntax check, which means that the second mailchecker:is_valid() call in misc:mod.rs never occurs.

Basically, misc.is_disposable isn't useful because all disposable email addresses fail the initial syntax check because mailchecker combines the two functions into one.
