Auto Post Via Email (Using Posterous)

I’m “trying” to post original content to my WordPress blog via the Posterous auto-post setup. Posterous says its possible and that WordPress works with them….but each time I setup my WordPress blog to auto-post via Posterous it ‘loses’ or drops the authentication with my WordPress blog.

I guess my question is really simple. Does WordPress work with Posterous or not? If the answer is yes it does…then I just need to keep trying to figure it out. If it’s no…I can stop.

Thanks.
