Q: Reset my Apple ID secret questions and No email received

Hello guys,

I'm trying to reset my Apple ID secret questions, everytime I click on reset by email, it prompts me an email has been sent to ur email "s******@thisdomain.exp" which by the way, looks OK but I never received any email ! (Had to try many times)

I checked everywhere inbox/spam/junk.. no result.

Further more, I own the domain "thisdomain.exp" (this is an example as you can guess), I check the catch-all email account and still no email from Apple - Which is really weird.

Many thanks, for your help !
