Q: Rescue Mailer doesn't received

Hi saadat.bahar,
 

Thanks for contributing to the Apple Support Communities.
 

It sounds like you're trying to reset your Apple ID security questions but you don't receive the rescue email.
 

In this case, you can contact Apple Support for help. See this advice from If you forgot the answers to your Apple ID security questions:
 

If you can't send a reset email, don't have a rescue email address, or can't access email at your rescue email address, call us for help. When you call, you might need to create a temporary support PIN to verify your identity. After you reset your security questions, you might want to update your rescue email address.

Sincerely.
