Regexp for email validation is to weak

[dpietrzyk]

I play around with this library, and I found a few cases where it returns that the email is valid, but they are invalid.

The code is simple

const ev = new EmailValidation({
  allowFreemail: true,
  allowDisposable: true,
});

export const isEmailValid = (email: string): boolean => {
  const result = ev.check(email);
  return result.valid;
};

Those are what I identified for now:

• 'user name@example.com',
• 'user..name@example.com',
• '.user@example.com',
• 'user@domain@example.com',
• 'user...name@domain.com',
