Hi,
A feature that is missing in James is the ability to export a complete
mailbox of a user.
We are going to implement it, using ZIP as an archive format with some
specific metadatas such as flags, uids.
Once the archive is generated, we had to find a way to warn the admin
(or the user) about the ability to download this archive. So we
conceived the following workflow
- An administrator generate an archive through the web admin API[1]. The
result of this operation is a task.
- This tasks generate a ZIP from the mailboxes and messages of the user,
and store it so that it can be downloaded.
- Once the task is finished, a mail is sent to the administrator (or the
user) to tell him the archive is ready to download
At the start and at the end of this process, an event will be fired to
make this process easily customizable.
This brings some security concerns, as the archive will contain
sensitive information, and so share its direct link by mail does not
seem a very good idea (and we don't handle user authentication on
webadmin for now).
So we chose to store the archive on an external service. For this first
implementation we chose LinShare[2], which is a FOSS software
specialized in file sharing.
Of course we'll welcome any contribution to an other implementation, and
we'll probably develop some other ourselves.
As you can expect we'll also implement restore to restore an archive to
an (empty) mailbox. Here the process is simpler:
- An administrator uploads an archive on a specific endpoint (parameter:
mailbox)
- If the mailbox is empty, the archive is restored.
The mailbox could be full in a future, allowing some partial
restoration.
Any thoughts / comments?
Regards,
Raphaël Ouazana.
