Why don't my DRM policies seem to work? Using "License Server for Protected Streaming"

Question

Do you find yourself setting rights/restrictions in a DRM policy (like disallow playback on Linux), only to see that the right/restriction isn't being enforced when you play your content?  There may be several reason causing this to happen:
1. If you are using the "Adobe Access Server for Protected Streaming" that came on your ESD/DVD, this streaming-only server is configured to specifically ignore any policy that was used to package content.  Instead, the server itself overrides the entire packaged policy and instead, reads rights from its tenant configuration XML file (flashaccess-tenant.xml) to generate licenses issued back to the requesting device.
2. Is your license server configured to use a PolicyUpdateList?  This is a list that can be used to override any old policy (according to its Policy ID) and to use a newly defined policy instead.  This is useful if content was pacakged with a policy and then afterwards, the business rules have changed for the particular policy, warranting an across-the-board change to all content packaged with that particular policy.  Using a PolicyUpdateList is essentially a way to version your older (already used) policies.
3. is your license server overriding the policy manually in its code?  If you're using the Reference Implementation license server (or building your own server from the SDK), your server has direct access to the policy.  The server can add/remove/change any right in the policy before using it to generate a license for the requesting device.  If you're using the Reference Implementation, by default, it will simply generate a license directly from the policy without any manipulation to it.
4. Are you sure you re-packaged your content using the new policy where you made your changes?  On your license server, since you have access to the policy (it's sent up to the license server as part of the license request), the license server can log the policy ID of the policy.  Check your logs to verify the new policy is actually being used.
5. Are you sure you're playing back the newly-packaged content?  Caches may be stale.

Answer 1

Not possible with a POP account.
The email account sync process with iTunes syncs (or transfers) email account setup information for select accounts only from your computer to the iPhone. This does not not involve messages.
The reason the account's Inbox mailbox seemed to sync is because received messages with a POP account are the only server stored messages and if not removed from the server when downloaded by one email client can be downloaded from the server by another - in this case the iPhone.
If you want Sent messages kept synchronized between your computer's email client and the iPhone's email client, you MUST use an IMAP account for this purpose.
