> Sure, using your own domain can open you up to mistakes. But at least, you're the one in charge. ...Of the management of the domain and the email itself. But if Google, Microsoft, or one of the other major email providers decides that you, someone else in your subnet, or even your ISP or VPS provider, is not following the rules they've decided are important, they can just...put you in a black hole. And you have no recourse. And your emails will simply never get to people using one of those providers, and you may not even know that it's happening without a user report. (Note that this is not me saying "And thus you should just give up and use Gmail." I still run my own email server, and I've managed to get it set up in such a way that it's mostly accepted by the megacorps, but it took months to figure out why it was even being blocked, and then I had to switch to a completely different VPS provider to get around the block. If there's a message here, it's "...and therefore we should break up the big providers under antitrust law, because no one should be allowed to be that big.")
