I thought some about this....

You don't need to tell her that you "won't be addressed that way". Since you can't control how she addresses you. But, when she is inappropriate, you don't have to respond. On the ring, for instance. Whether you answer or not doesn't impact you. So, if you think her email was inappropriate, you just don't respond. Sometimes, of course, there may not be much choice. In which case you just answer the critical questions, and ignore the rest. Let her burn herself out on her negativity. Don't take the bait.
