OT: "domain-level" email hosting services?

[Ofer Inbar]

I run postfix on a cheap cloud-hosted linux instance.  That does mean
I sometimes have to deal with deliverability issues which can be annoying.
However, I've searched for a more fully managed email hosting service
that would let me see my logs, including logs of attempts to connect
to deliver to my domain(s), and I don't think such a thing exists.
I value the ability to tail -f my mail server logs enough to make it
worth it to me to run my own server.
