Scenario : Sponser based approval for guest users. guest should input email id for regestration.

Question : Is it possible to prevent guest users from using sponsor email id in guest user emaiID field? Some sponsors are miss using this feature by creating guest accounts with their own acconts

Why don't you just block email requests from your sponsor's domain?

Thanks for the info.But in  a scenario where sponsor and Employee user (Captive Portal Login) belongs to same email domain and already a domain based restriction is applies to both sponsor and Employee registration page field using "Isvalidemail" validator(Code given below) as mentioned by you, can we restrict the sponsor and Employee user mail ID entered by the Employee user in the registration fied from being put the same email ID or in simple terms can we restrict the employee from putting his email ID in both sponsor and user email Field and thus approving his own account.

array (
  'allow' =>
  array (
    0 => 'companydomainname.com',
  ),
  'deny' =>
  array (
    0 => '*',
  ),
)

Is there any solution for the above case?
