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.
Tommy,
There is no way to limit out-bound messages - at least not in the current version. They will get sent right away.
How often do you have to restore these messages? Did they get incorrectly blocked by Xeams?
