Where is default STORAGE_ROOT ? What are default install locations?

[mib16]

Hi,
where is STORAGE ROOT for mailboxes ? What are default install locations of other components of miab ? (or where can I see defaults on github ?)

I want to install at minimum mailbox dirs to encrypted partition (so mails are safe when e.g. server stolen).

Thank you very much for reply&help.

The main directory for all information is:
/home/user-data

With mailboxes specifically inside:
/home/user-data/mail/mailboxes

Each domain will be a subdirectory inside here with the actual username yet another subdirectory inside the domain.

There are some components and configurations outside this (i.e. nsd and DNS zone files, among others).
