Mail.cfc, when used in Coldbox 7 retrieves getInstance( "Renderer@coldbox" )to render views and layouts, however that results in retrieving an instance where the Renderer has not been started.

Two things should probably happen:

1. For legacy code, the binder mapping in LoaderService should probably return the started instance

2. cbmailServices Mail.cfc should inject coldbox:renderer which is the started instance and use that.
