A customer request requires us to doctor the "To:" list based on certain criteria. I have the code working, but now there is a substantial body of code stuck in the template and so subject to loss/corruption.

It would be nice if Pre-Send supported Classpath additions like Groovy Postbuild Plugin and/or Groovy (Executor) Plugin. That way the bulk of the code could existing under source control and the actual Pre-Send script could be little more than:

def obj = new MyClass();
obj.Execute();
