It's unfortunate that email hosting and email infrastructure can really be done only well by major players. The days of people running and maintaining their own are pretty much long gone. Fwiw, not a knock against CF. I like their products, mostly simple, fair pricing, etc. Just a bit unfortunate commentary on the state of email infra on the internet.
I do, too. What I don't like is that they became too large and now are effectively in position to gatekeep the whole internet.
