I'll add my voice to the Fastmail love. I've connected a couple of domains to my Standard $50/year (plus VAT) account, and as long as you follow all of their directions on adding SPF and DKIM settings to your domain, it works like a champ. Setting up on-the-fly aliasing for my domains was also just a matter of following their directions, and I love the looks I get when I fill in [businessname]@[mydomain.com]. A middle-aged lady engaging in email nerdery really subverts expectations - I tell them if they're really hesitant to accept that address with their business's name in it that it's an organizational tool for me (true) with a bonus of free hacking detection for them (possibly true). I do not say that the main reason is that I do not trust them to never ever misuse or lose control of my data.
