iSheriff^TM version 5.2 - New features

• Multiple time zone support - Individual realms and workgroups may be assigned time zones relative to their locality in order for filters and reports to be scheduled more accurately. This setting is independent of the actual system clock time allowing for servers to be logically or physically located in chronographically independent locations. Time-of-day filter rules are applied according to the individual time zone offset of the realm rather than the time zone of the server. Reports are automatically adjusted to offset the time axis to show the data in the local time zone context for the particular user group requested.
  
• Clustering - Clustering provides the ability to maintain an array of servers as a single cluster with centralised management. Distribution of configuration data is fully automated, greatly reducing systems management overhead. Changes made to a live running system are automatically propagated on demand to every server in the cluster, providing a consistent filtering experience for end-users. Statistics from all machines are automatically aggregated to provide system-wide reports for the entire user-base. In addition to the system management interfaces (Web and CLI), configuration files may also be edited by any external means (vi, scripts, PHP, web portals etc) and the changes will be automatically detected and propagated to the entire cluster, even if a server is offline at the time.
  
• Database support for reporting - Reporting data may now be optionally stored in a database for greater scalability and efficiency. The use of a database backend in larger installations provides for more uniform end-user response times when generating reports. As for a non-database installation, reports may be generated on demand and will display near real-time data, or may be scheduled to run automatically in batch mode. This option also allows for access to the raw data via SQL, third party tools, or custom database access routines.
  
  Presently the MySQL database is supported natively. Other databases may become available in future versions. The original iSheriff proprietary data file format is still supported and is recommended for smaller installations or where simplicity is desired.
  
• Extended custom email lists - Individual realms and workgroups may now be assigned an unlimited number of private custom email lists not visible to other realms. These lists may then be used for filtering purposes as allow lists, or deny lists or with other actions as appropriate.
  
• Group alias quarantine recipients -Quarantine notices directed to a group or list alias (e.g. info@, sales@ etc) are now able to have a single nominated recipient specified. This overcomes the issue of multiple users receiving the same notification for a single mailbox, reducing unwanted notices and administration overheads.
  
• Email grey-listing - An enhancement to the effectiveness of email filtering of spam and viruses, grey-listing postpones delivery of suspect emails at the SMTP communication layer. This approach is highly effective and blocks spam attacks at the earliest possible point during delivery, greatly reducing the load and volume of spam for processing by further deep inspection filters. Spam outbreaks can be reduced in volume by as much as 90% by this means alone.
