I am not sure what you mean by "connected with the Apple ID in use". The email aliases were email aliases that I had with MobileMe and they carried over to icloud. Email sent to either the original Apple ID or the email alias has always worked as expected. The email shows up on IOS devices and my Mac regardless of whether the email was addressed to the original Apple ID or the email alias.
