I wouldn't normally advocate this, but have you tried the non-response tactic? I've been doing it lately; instead of just piling in straight away with a response I let things brew for a while. It's amazing how many times something else happens to make my response unnecessary!

If she's sending out these edicts that you should all do something a certain way and you ignore it, what is going to happen? Either she e-mails you again - which you can also ignore - or she will speak to you. I would be surprised if she chose to speak to you because people like this usually know on some level what they are doing and don't want to confront it. If she does speak, you say something along the lines of 'I didn't think you were serious when it goes against company policy'. If she insists, you say 'Well, e-mail me with what you want, why you want it and your reponses to my points so I have it all clear in my mind and I'll do it."
