Files are stored on the BlueMind server, in the directory
Files are stored in sub-folders by User Identifier (UID), with the path
Note that folders for users migrated from BlueMind 3.0 will be shown as
/u/user_entity_XXX and folders for users created in version 3.5 will be shown as
Files stored in this way are not accounted for in user quotas – which only apply to emails – whether the Drive feature – the possibility to find folders later on – is enabled or not.
As a result, depending on usage and the install's number of users, this can take a lot of space. In order to prevent disk space overload, we recommend that you create a disk mount that allows you to store data externally which you set up monitoring for.
Installing the packages
In a default BlueMind install, sending email attachments as links is not available to all users. To let them access this feature, you must install the required packages and restart the server:
As things stand, files are stored on the BlueMind server itself. A connection with Nextcloud is also possible.
In the future, BlueMind will enable interconnection with other external file sharing services such as Dropbox, ownCloud, Pydio, etc.
Defining the file hosting server
BlueMind must be told which server must be used to store the files remotely. To do this, you must give the desired server the "Filehosting data" role, even if you are in a single server architecture.
- log in as admin0
- go to System Management > Application Server > [select server] > "Server roles" tab
- in the "BM services" section, check "Filehosting data":
Enabling the service for the domain
Once the server has been defined, the service must be enabled for the desired domain(s).
To do this, go to System Management > Manage Domains > select a domain > "BM Services" tab and set the server whose role you've enabled before using the drop-down list:
Enabling the features for users
Once the packages are installed, the feature must be enabled for users. This is done by assigning them the appropriate role. Linked attachments (remote attachments) can be enabled for all users or specific ones only, individually or through groups.
Two new additional rights are available:
- Remote attachments: allows users to detach and link files to email messages.
- Drive: gives access to BlueMind's file browser. Users can browse previously sent files and link them into new messages.
This saves disk space as the same file is not stored multiple times.
In the admin console, go to the entities management section > Directory browser:
- Choose the group or user you want to assign a role to.
- Go to the roles management section:
- For groups, go to the "Roles" tab
- For users, stay in the "General" tab and scroll down to the "Roles" section
- In the "CLOUD" section, check the features you want to enable:
The linked attachment feature can be set up in several areas of the admin console:
- In System management > System Configuration > Filehosting tab: this tab is used to set the default values for newly created domains, it does not set or override the values for all domains.
- In System management > Manage Domains > <choose a domain> > Filehosting tab: this tab is used to set the default values for the chosen domain.
Once the packages are installed and roles are assigned, users have access to the linked attachments feature with a default maximum file size of 5MiB.
To change this limit and access more configuration options:
- log into BlueMind as admin0
- go to System Management > System Configuration > Filehosting tab:
- Retention time (days): number of days files will be kept on the server, from the original sent date.
- Auto detachment limit (MiB): size for which email attachments are automatically added as links
- Maximum detached attachment size (MiB): maximum file size permitted.
This is the maximum size permitted per file, several files whose total size exceeds the limit can be attached to and detached from a single email message provided each individual file does not exceed the limit.
- Backup File hosting data: if this box is checked, the storage folder on the server will be included in BlueMind backup tasks.
The MiB (mebibyte) is a multiple of a byte, not to be confused with the MB (megabyte): it equals 1,024 kibibytes, which equals 1,024 bytes.
Therefore, 9 MiB equal 9.43718 MB
