From what I can tell, one of these newer emails done through the same mailserver as the others seems to be advertising the MakeBTC webhost, as alleged by MakeBTC theirself. If this is any solid proof, which it isn't necessarily, then it may indeed be their host who is causing all this trouble, and I'm swayed to agree until proof to the contrary appears.
Also, after refreshing my inbox it seems an email from "BTC square" with a 'reflink' to the previously mentioned Site #2 (engineerinv) with the exact same sender.
