They are using stalwart, another open source product, for the backend stack. So you should be able to host your own server instance with custom domain when it gets built out. Stalwart itself just received a European funding grant to build out the features needed. From Thunderbird announcement:
> Thundermail is an email service. We want to provide email accounts to those that love Thunderbird, and we believe that we are capable of providing a better service than the other providers out there, that aligns with our values. We have been experimenting with this for a while now and are using Stalwart as the software stack we are building upon. We have been working with the Stalwart maintainer to improve its capabilities (for instance, we have pushed hard on calendar and contacts being a core piece of the stack).

Imagine maintaining a useful piece of FOSS and then Mozilla shows up and "pushes hard" for some feature they want for a service that's missed the boat by a decade and doesn't even elicit much hope from loyal users (including myself).
Stalwart is unique I think. The whole thing was built by essentially one developer in rust, and it's quite amazing how he has done it in just a few years. He's expressed interest in expanding the software beyond email in the past, and contacts/calendar/files shouldn't be too hard of a challenge for him.
That's a bit negative. There are plenty of people that want a full OSS alternative to Gmail, Outlook, Yahoo and others. That includes calendar and contacts.
