DCC servers

[JohnMertz]

As is the case with the current version of MailCleaner, there are not any valid configured DCC servers. According to the terms of the DCC license, MailCleaner must provide our own DCC servers or contract with a public provider. It is somewhat unclear whether this applies to Community Edition, since that would not constitute a resale (since there is no sale on our part), but the spirit of the license seems to indicate that it should not be our place as a vendor to enable this by default.

In my eyes, I think that we should provide GUI configuration of DCC servers which are undefined by default. We should set up DCC servers for our Enterprise clients which populate upon registration. Otherwise it is up to the admin of the Community Edition appliance to enable DCC servers in good faith.
