Implement an mbox backend worker. Worker can be used for testing and
development by mocking a backend for the message store. Worker does not
modify the actual mbox file on disk; all operations are performed in
memory.
To use the mbox backend, create an mbox account in the accounts.conf
where the source uses the "mbox://" scheme, such as
source = mbox://~/mbox/
or
source = mbox://~/mbox/file.mbox
If the mbox source points to a directory, all files in this directory
with the .mbox suffix will be opened as folders.
If an outgoing smtp server is defined for the mbox account, replies can
be sent to emails that are stored in the mbox file.
