Can I configure askbot to not send out duplicate emails?

edit

Since I'm one of the forum admins, I have most notifications enabled. When I answer questions, I follow them and also use the "email me updates" check box. I've noticed that this causes duplicate mails quite a few times (once because there was some activity on the question, once because I'm subscribed to all forum activity etcetera). Is it possible to get askbot to realize this and only send out the mail once or would this be something I need to do in my mail back-end (we use django-post-office)?

Here's a screen-shot. I have 4 emails from askfedora. It should ideally be 2. If you look at them, each "notification" has come down to me twice. I'm guessing once because I had "email updates" enabled, and the other because I have notifications from the "entire forum" enabled too. I checked the mails, they have exactly the same content.
