I'm looking for a place to run an instance of Mail in a box (https://github.com/freedatafound/mailinabox). Where do you think is the best place to host it?
It's difficult to tell which is the best, but there are good resources for finding which hosting providers to avoid. You'll just have to evaluate the hosts you like one by one.
A host with more issues means it is more likely that you'll get painted with a "spammer" brush.
And then, of course, do all of the right things. SPF, DKIM, setup TLS correctly and so on. There are plenty of documents available discussing this. I presume mailinabox takes care of a lot of this for you.
It really depends on your security model. If you're not too concerned about the authorities, then a digital ocean box should be fine. Otherwise, I'd go with an offshore host. I haven't used them personally, but I've heard good things about http://undergroundprivate.com
