Perhaps I can run tests on a *clone* of Uncensored's db. Over the last two days I've seen the problem begin after the 04:00 hour; this happens to be when we run TDAP so it's definitely possible that we're looking at a memory issue of some sort. It might even be a massive memory leak triggered by TDAP, but I'm really suspicious as to why the only thing it seems to be affecting is outbound mail delivery.
