New in BlueMind 4.5
Video-conferences with Jitsi and StarLeaf
BlueMind 4.5 brings the possibility to link a Jitsi or StarLeaf server to a domain so that users can generate and link video-conferences to their calendar events:
To find out more about using it in the Calendar, please go to our User's Guide page: Linking a Video-Conference to an Event.
Read/unread status for shared mailboxes
For improved clarity and not to disrupt the habits of users who are familiar with other mail systems, the read/unread indicators for shared mailboxes are now the same for all the users of a shared mailbox.
This behavior can no longer be configured by administrators.
Shared inboxes in Outlook
Shared inboxes are now shown as shared mailboxes in Outlook's main folder list and no longer in the "Public Folders" section:
To make the work of BlueMind administrators and integrators easier, maintenance – such as repairing some users – can now be performed automatically through hot updates. As a result, maintenance operations do not interfere update processes or production resumption.
Seamless maintenance operations
Database maintenance and production processes now run in parallel so that production isn't interrupted. Maintenance is now fully controlled by a planned task, which can be seen and disabled by the administrator and no longer causes disruptions for users.
No user-log out during BlueMind restarts
Users are no longer logged out when BlueMind is restarted. System disruptions during a hot fix or update are minimized for end-users who no longer lose work in progress (e.g. an email being written).
New in BlueMind 4.4

Please try it now, we'd love to hear your feedback!
Proposing new dates
Being able to make a counter proposal to a meeting time/date is finally possible! It is compatible with calendars that support this feature through BlueMind's webmail and with Outlook over MAPI and Thunderbird!
The meeting's organizer stays in control of whether to let invitees suggest a new time.
In Outlook, invitees and the organizer can use the usual event-response tools to send/accept/decline a proposal:
The double-bottom trash folder lets users recover deleted items. It includes a server-side delay during which deleted emails are kept – during that time, users can retrieve messages from their Outlook client (over MAPI) or the administrator can retrieve them from the server in command line (see below).
This feature will be implemented in the new BlueMind webmail application in an upcoming version.
In addition to bug fixes, this new version comes with new features now available in Outlook over MAPI.
Rich text out-of-the-office message
Out-of-the-office autoreplies configured in Outlook can now be written in HTML format. Users can now choose between text format (the only available until now) and rich text format (bold, italic, color, text size, image, etc.).
Restoring deleted messages
New Outlook feature: users can access the list of recently-deleted messages and restore them (unexpunge).
For more details, please refer to the section above "Double-bottom trash".
Tags are now imported during calendar and event ICS imports.
Default domain time zone
Administrators can now specify a time zone for a domain. The time zone becomes the default time zone for new users as well as existing users using the previous time zone (when it is changed).
To find out more, please refer to the page on Managing Domains.
Modifying the domain name displayed
Since BlueMind's version 4.3, in order to allow administrators to update their domains, all new domains are created with a unique identifier generated automatically ("XXXXX.internal"). In that version, the admin interface would show the first alias as the domain name, and the internal identifier stayed on most pages.
From version 4.4, domains have an identifier (XXXXX.internal), one or several aliases including one default alias. This default alias can be chosen and changed in the admin console.
Address creation pages have been adapted and simplified to use the default alias and not show the technical domain name.
For more details, please refer to the page on Managing Domains.
HTTP Proxy support
In some scenarios, such as external calendar queries, some installs require an HTTP proxy server.
Once the HTTP server is configured and enabled in the admin console (System Management > System Configuration), external requests made by BlueMind pass through BlueMind.
For more details, please refer to the page on System Configuration.
Command line admin tool (bm-cli)
Command line support of the double-bottom trash folder
As outlined above, the double-bottom trash folder has a delay on the server side – the server keeps deleted emails for a certain time, which means that they can be retrieved by some clients or administrators.
A new command is used to retrieve messages that users have deleted but have not been permanently deleted by Cyrus:
bm-cli mail unexpunge.
This bm-cli command is necessary because the Cyrus "unexpunge" command, which seemingly does the same thing, does not return enough information for the replication protocol and breaks the link between Cyrus and BlueMind.
To find out more, please refer to our Knowledge Base page on Restoring messages deleted by a user.
In addition to being able to restore deleted messages, the new version brings several improvements and new commands.
New commands and options:
server tag / untag / add: used to make adding servers automatic and enable server tagging actions (e.g. mail/imap).
main reindexpending: used to reindex the "mailspool_pending" index
user import / export: used to import/export to/from Cyrus archives
setup install --admin0-pass: lets you define the admin0 password on installation. E.g.: bm-cli setup install
bm-cli index infocommand no longer counts deleted messages.
- The --addressbook-uid option for the "
contact import" and "
contact reset" commands supports domain address books: you can now import VCF files to a domain address book and reset the domain address book.
- The airlift library is replaced by the picocli library. This library enables improvements such as support for the
- Color schemas have been improved and all error messages are now sent to the standard error stream.
Progress information is now sent to the standard error stream (
stderr). That way json data is generated for the command concerned, e.g.:
Shared mailbox repairs
Administrators can now repair shared mailboxes the same way they are used to repairing users.
New monitoring dashboards have been added for Elasticsearch and PostgreSQL:
- The "ElasticSearch" dashboard lets you view the status of the ElasticSearch cluster and its activity.
- The "ElasticSearch Mailspool" dashboard is more specifically designed to monitor BlueMind mail, it is used to diagnose issues with user distribution balancing in the indexes.
- The "PostgreSQL" dashboard is used to monitor the status of the PostgreSQL cluster.
In addition, the admin console's monitoring page now shows TICK alerts:
- ElasticSearch storage has been improved by reducing the amount of data saved in ElasticSearch – some fields used to be unnecessarily stored several times. For this reduction to be effective, re-indexing is required.
- The "mailspool_pending" schema has been updated, which means that documents don't have to be indexed from mailspool_pending. With 339,315 documents, the space used goes down from 741MB to 267MB while CPU load is reduced.
The ElasticSearch cluster status can switch to "red" when disk space is running out. When extra space is added, the cluster now switches back to "green" automatically thanks to a Kapacitor alert.
This version brings Java support for the Sentry error reporting system: improved error reports, with stacktraces as appropriate, are sent to the Sentry error management system.
Sentry reporting can be enabled using the following command:
Sentry error reporting is disabled by default.
Outgoing port security
Outgoing email ports (ports TCP 465 and 587) now use version TLS v1.2 at least.
For protocol purposes, a test suite has been implemented in BlueMind to further improve our testing tools and make them more like to the Microsoft protocol yet.
