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.
It's only a problem when you don't know who the association is for. It just seems odd that mail in an outbound queue for user x@abc.com would show up as being for an alias. It seems it must have been extra effort to code this!
