What information would you gain from sending a test email? Wouldn't test emails sent to Apple's anonymous forwarding email also go through?
There's really no such thing as checking for a "real" email address, though lots of sites do blacklist known anonymous email domains like 10minutemail. But nothing can stop you from just signing up for a new Gmail.
- spacehunt 7y agoSenders to Apple's email proxy needs to be pre-registered first (and I highly suspect the generated addresses are scoped to each individual app's whitelist), so no, not everyone can send to those addresses.
- laughinghan 7y agoThe sender already is pre-registered. We're talking about users who have successfully Signed In With Apple ID.
- cglace 7y agoAfter signing up you would request a non proxy email. Hence, the “real” email. You would then test that the user supplied email is legit.
- laughinghan 7y agoBut nothing is stopping the user from supplying a proxy email address in your textbox where you ask for a non-proxy email address. Sending a test email doesn't tell you whether the user-supplied email address is a proxy email address or a non-proxy email address, since your test email will go through in either case. That's the whole point of a proxy email address instead of a completely fake email address, is that emails sent to the proxy email address will still go through.
