I highly recommend Fastmail [0] for this purpose. I have been with them for 5 years, and they're rock solid. I have ~10 domains on it, they support wildcards (send/recv at [email protected]), the composer has sane defaults for multiple domains (e.g. replies are sent from the address it was mailed to) that can be overridden when you need, and you can easily create masked emails using your own domain.
$50/yr for all that is a steal. They don't charge you per-domain or have any funky tiered pricing for the stuff that matters.
Disclaimer: I am not related to them, just a happy customer :-)
