Hi Rzwahr,
If you find a way to do this, let us know. There might be some way to set up a public folder to post it, but my guess is that there is some security reason why this can't be done. Why not just have 2 submits from the form? First submit to SharePoint and then send e-mail. We do *that* (dual submits) all of the time.
