The parent Object could be coming from the Configuration container object
(use ADSI edit to look at it). But think of it as being set by the Exchange
Full Administrator permissions. I would not recommend changing settings
anywhere else.

To achieve the result you are after just add a Deny Send As permission in
ESM (which is the default for Exchange Full Admins) and that will stop the
ability of a Domain Administrator to open another users mailbox.

As to Send As on the Security Tab in AD -note this is different to the Send
as in ESM- , if you have full control of an OU object, you will
automatically inherit the ability to Send As any user created in that OU. If
you do not have full mailbox access or the ESM rights you will not be able
to view the email in the mailbox, but you can spoof email as any user in the
OU.

Also note you can increase the logging in ESM to track the use of Send As
(it will log it to the Event Viewer). Server properties, Diagnostic logging,
MSExchangeIS, Mailbox, Send As.
