Hi everyone,

I have the following issue in our Exchange 2013 with Domain controller 2012 environment.

If i configure the receive connector (Default FrontEnd servername) to accept Exchange server permission group (or every group except Exchange users ), so no user in  active directory Should not be able use smtp,Imap in outlook.

this is true.

but when add a user in domain admins group or enetrprise admins group, that user can connect to smtp exchange with outlook and send e-mail without problem.but permission in  receive connector (Default FrontEnd)  to accept Exchange users permission group not set.

How is this possible
