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.
I found a solution to this problem. Albeit a bit late, but it might perhaps help other users with the same problem.
Set up port 587 on XEAMS, make sure START/TLS is enabled.
