There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
Go to Filter Management/Adaptive Filters/Auto-Learn Sender Filter to turn it off.
