appleid@id.apple.com emails to be forwarded
Hello!
I'm trying to forward emails from appleid@id.apple.com to another email address.
Currently, the emails from appleid@id.apple.com are being sent to my iCloud Mail account via my Apple ID login.
The email address I would like them to be forwarded too is gMail.
Everytime I try and set-up a rule, I receive the following error message:
The error message appears to be directly linked to the appleid@id.apple.com rule because as you can see, forwarding has worked absolutely fine for two other rules.
Any assistance would be great.
1. Does anyone else experience this error?
2. If so, is there a workaround?
3. Or is this 'expected behaviour'
