Just seeing if anyone is still interested in this request?  I know that we're still in need of it.

Yes, here's a similar request for basically the same thing -- forward as attachment...

Apologies for the delay on this, I found this posting and the post regarding forwards with headers this afternoon, and I have now submitted this as an official feature request to our development team. Keep an eye out for release notes in the future as this is likely how you'll hear about this addition. Thanks for the suggestion!
