+== Allow users to have rights for shares of different domain
+
+Typically, preventing users to obtain rights for shares of another domain is a
useful security layer.
+However, in multi-tenancy deployments, this can be useful (for example,
students might be given access to a shared mailbox
+residing under the @university.edu domain with their @student.university.edu
address).

Review Comment:
How about naming this
```
james.rights.crossdomain.allow=false
```

Make it a constant: looking this up at class loading is enough

Review Comment:
Ah ok I got it, that's needed because of the tests!
My suggestion is to allow the constant to be package local mutable annotated
with `@VisibleForTesting` so that overloading that in tests become easy while
keeping the property lookup at classloading time.
WDYT?
