I'm also using Zoho, since it was the only provider I could find that let me use my own domain for free. It's been working great so far. Up until fairly recently, I was using Pawnmail (https://news.ycombinator.com/item?id=8548307 https://news.ycombinator.com/item?id=8548307), but it became very unreliable. Half of my sent mail bounced, and then it just stopped working altogether. I use Thunderbird as a client.
