To do this right you should also think of backups, updates, and monitoring. Self-hosting is true freedom but doing it right for things like email is akin to running a small business. On the positive side docker makes many things a breeze.

I tried with Docker before and it is not a breeze as you think it is. I tried to use Docker for Calibre-Web and it is a pain to make it work. Because Calibre-Web required to access their database in the filesystem outside of Docker. Docker provided minimal (more of lacking) information of how to expose the filesystem for Calibre-Web to use their database. Calibre-Web cannot create their own database, it relies on Calibre, standalone app, to generate the library that it need to have access to. It took me ages to finally to find a way to expose the filesystem and only provide permission to access that particular library.

I am surprised by this shortcoming of Calibre image. I guess the trade is learning how to install calibre vs. learning how to deal with docker. I'd also agree that even if you use docker and installation is easy - for any self hosted apps you are using for a long enough time you end up learning enough about them to be able to install without docker (and avoid managing docker in addition to everything else).

Calibre does have their "book sharing" solution that are built in the software. However it is more like content server. Calibre-Web is a third-party solution that are not affiliated with Kovid Goyal (creator/main developer of calibre). And Calibre-Web is basically browser version of Calibre without requiring other people to use Calibre to access Calibre-Web. So Kovid did not create this calibre-web image from what I understand.
