forwarded email rejected by icloud
Hi. I'm new to icloud as have set up an account as travelling to China and dont want to expose my real email account whic is a microsoft exchange one. On my Microsoft account i have created a forwarding rule to formward everythnig to my icloud account. Oddly some of them are getting rejected with "Security or policy settings at icloud.com have rejected your message." these are mostly advertisemnt type messages with lots of pictures. However if I manually forward the message it works fine.
error detials
Error:
554 5.7.1 [HM08] Message rejected due to local policy. Please visit Postmaster information for iCloud Mail - Apple Support
Message rejected by:
p00-iscream-smtp-6d5b65db57-ljk22
I dont really understand the error but its like it identified the sender or typeof mail as being spam like. can I white list my Microsoft email so all main gets accepted?
Thanks for any advice
