It would be great if there was some PaaS-type mail service provider. I'd like to get away from hosting it with a single VPS, and running multiple VPSes for redundancy seems frustratingly expensive for such low-intensity load like a personal email server. Ideally, I'd sign up with one or two services and have each listed as an MX for my domain so there's always some service online to take the email. I can write my own app to hit both services and unify the two streams.

That sounds pretty cool actually. Assuming two servers had equal weight in MX records, such that mail had a 50/50 chance of going to either, you could unify it via fetchmail, or similar, if you polled both backends directly. Usually it is a pain if you have mail going to more than one host - ie. no shared storage amongst all the hosts that receive mails, but if you were looking for redundancy and didn't mind the "manual fixup" this would be almost trivial to setup with 2+ VPS from different providers.
