Libraesva EA v21.03: Release Notes

Changes in EA v21.03

 Main Features

• New “report” feature to request a tenant statistic report
  The report is an Excel spreadheed with tenant usage information (emails and storage), per-user usage information (emails and storage), charts of usage over time (emails and storage)
• New native Zimbra connector
  Uses the native Zibra APIs to sync email, folders and for message restore
• Office 365 user delegation using custom schema extensions
  A user can now be delegated to manage other mailboxes.
• Recipient-based SMTP listener authentication
  The attribution to the tenant can be based on the recipient of the journal email. For example: journals delivered to tenant1@archiver.mydomain.com are attributed to tenant1, journals delivered to tenant2@archiver.mydomain.com to tenant 2

Features

• Delay update until all running jobs are completed
  Automatic nightly system updates are postponed until all running import/export jobs are completed
• Automatically suspend services when engine disk usage is higher than 90%
  In order to avoid data corruption, the archiver will stop ingesting more email if the disk is getting full. The administrator is notified in advance.
• Handle IMAP corrupted messages
  Better support of less-than-perfect IMAP implementations
• Compress folder structure dump while preparing it
  The backup of the folder structure requires much less disk space and reduces disk I/O
• Support mailbox-based licensing
  Introduces a new license based on the number of mailboxes rather than on the storage size
• Compress logs to reduce engine disk usage
  System logs are now stored in a compressed format reducing disk usage
• Add support for zip-based reindex
  The granularity of the reindexing process is now higher
• Add tenant soft and hard deletion
  Tenant deletion is performed through a quick soft-delete followed by a background process of hard-delete
• Add customer address list in tenant summary page
  Besides showing the number of messages, addresses, listeners and connectors related to the tenant, now the tenant summary page can also list the addresses
• Add notification snooze settings
  Notifications can be snoozed with a very high level of granularity
• Add support for additional data disks
  The console menu allows to add disks to the Archiver VM
• Improve job error notifications and logging
  More information available to the admin about job execution
• IMAP journaling skips duplicated, already imported, messages
  After having verified that the message is actually already present in the archiver, the duplicate message is skipped
• Send notification on automatic index check failures
  Index health checks are automatically performed and issues notified to the admin
• Keep historical, per tenant, disks usage and emails count statistics
  Besides appliance-wide historical usage data, also per-tenant historical usage data is calculated and stored
• More logging for outlook-addin authentication failures and email parsing failures
  Debugging these kind of issues is now faster thanks to more details provided to the admin
• Synchronization for a single connector can be launched
  The admin can force a synchronization execution for a single connector, without waiting for the nightly sync
• Add message IDs dump to backup procedure to speed up the restore (and reindex) process
  With this additional information in the backup, the restore is much faster
• Re-design SMTP listener configuration page
  UI redesign for a better user experience
• Delegation support in outlook-addin
  Delegated users can manage other mailboxes also from within the outoook-addin
