Is there a way to override Sieve's "not sending notification for auto-submitted message" behavior?

I also thought about creating some sort of filter/milter to just strip out the header for those emails before letting the Sieve filter handle the rest, but I've not yet had a chance to research just how to go about that.

So yea if you're on postfix I don't know of better/other terms to think of this in.
In exim, you could send out a notification and/or strip/add/modify headers without any external script or writing any "code" per se, just within exim's config file.
Although writing a milter for postfix isn't all that complicated either.
Postfix has [ ], you can use that to remove a header (IGNORE), you just might be able to set that up to test for the right conditions *when* to do this, and then proceed to remove the header. Gotta run now so I can't put more thought into it at the moment but do post if you figure it out :D
