Have you actually tested this policy, by going logging into an iCloud account and clicking the mail tab.? The rule you have (same one I have) will block a mail client (outlook/thunderbird etc) from communicating through the standard ports,(25/110/143/587/993) but will it a block a web browser tab opening email?

So blocking the www.icloud.com<http://www.icloud.com> url is not an option, anyone have any pointers? TIA
