Google is eating our email
So why am I writing all of this? Unfortunately, email is starting to become synonymous with Google's mail, and Google's machines have decided that mail from my server is simply not worth receiving. Being a good administrator and a well-behaved player on the network is no longer enough. This is already a big philosphical problem now, and it will only get worse as large tech companies try to wrestle ever more control over the web away from users. And because this sort of stuff is so low-level and technical, it's not going to grab headlines or stirr the masses.
