The problem is that the recipe build uploads are not conforming to the existing email rules. There's a very specific set of rules that source uploads have and when we start doing recipe builds for Ubuntu, they must persist. However, sending emails for each recipe build itself seems to be wrong, and should probably stop - the only occasion you should get an email from those is if they fail, in the same way that binary package build notification emails work.
