Comment 12 for bug 181948

The code in the patch looks fine, but the debdiff does not apply to the exim4 package. exim4 uses a packaging approach I'm not terribly familiar with, so I'd not trust myself to repackage the patch to suit; someone more familiar with the packaging process for exim4 needs to look at this. DHolbach, can you please find someone to sponsor it (or unsub ubuntu-main-sponsors until someone can produce a proper patch)?
