v2.1.0

• Fix bug where addresses containing unquoted Unicode punctuation or symbol characters in the local-part would be incorrectly considered valid (Thanks @acmcmurray for reporting and @houssam966 for contributing! 🎉).
  • While RFC 6531 allows for UTF-8 characters for the purposes of internationalized domain names, not all Unicode symbols are permitted.
    Specifically, this excludes Punctuation (Pc, Pd, Ps, Pe, Pi, Pf, Po) and Symbols (Sm, Sc, Sk, So).
• Fix bug where the validation rules requireOnlyTopLevelDomains() and disallowReservedDomains() did not correctly ignore case in the domains (Thanks @mtillberg for contributing! 🎉).
• Fix bug where the order of validation rules added to an EmailValidator was not properly maintained. This resulted in rules being applied in an arbitrary order during
  validation instead of the intended order (Thanks @Gedankendreher for reporting!).
• Add new ValidationRule disallowDisposableDomains(DisposableDomainSource) to consider email addresses that have a disposable domain (such as [email protected]) as invalid.
  • The DisposableDomainSource.file(String) implementation of DisposableDomainSource uses a given file as the source of truth for disposable domains (Thanks @mtillberg for contributing! 🎉).
  • The DisposableDomainSource.inputStream(InputStream) implementation of DisposableDomainSource uses a given InputStream as the source of truth for disposable domains (Thanks @liias for contributing! 🎉)
  • The IsTempMailAPISource uses the IsTempMail API as the source of truth for disposable domains. Usage of this source requires an API Key provided by IsTempMail.
