• Sender Policy Framework (SPF) checks
• NJABL real-time black list tests
• Sender address verification
• Recipient address verification
• Sender domain validation

• Thorough spam control for all messages (including POP3).
• New rule structure allows that allows arbitrary combination of criterias and reuse of actions.
• Addition of message stamps (eg. disclaimers) to any/all messages passing through the NetBox.
• Client IP/network based rule criteria.
• Protcol based rule criteria (SMTP or POP3).
• Attachment type selection for text searches.
• Sender and recipient address matching.
• Configurable message encoding fault detection.
• Customisable alert messages. Unique alerts can be used for each rule action.

• Header match critera: Allows matching against any message headers. Also allows wildcard matching.
• Message size criteria: Allows matching of messages greater than, smaller than or equal to a certain size.
• Number of recipients criteria: Allows matching of messages based on the number of recipients.
• New message stamp algorithm: The algorithm for adding message stamps to messages has been reworked to provide compatibility with a wider range of email clients.
• SPF Optimisation: The internal processes for performing Sender Policy Framework (SPF) checks have been optimised to improve throughput and reduce impact on overall system performance.

This release introduces a new reporting module for all NetBoxes. The reporting module allows configuration of reports concerning many aspects of the NetBox. Statistics available include virus detections, spam block activity, Internet link usage and link uptime information. More report types will become available in future software releases.

Reports include a mix of textual and graphical data and may be delivered by email or displayed on-demand through the web interface. A schedule can be configured so that reports are sent to specific email addresses on a periodic basis.

Once this release is installed on a NetBox, a detailed report will be automatically configured and sent to the administrator alert address every week. The available reports can be configured under Reporting > reports in the web interface. The report schedule can be modified under Reporting > schedule.

Parts of the Reporting module were optimised to improve report generation speed and increase data collection efficiency at busy sites.

• Some minor header unfolding bugs were fixed.
• Received header analysis was restructured to improve robustness in certain situations.
• The default "Unwanted Content" action no longer sends an alert if the triggering message was received via POP3.

A new NetBox module is now available to allow for flexible web access policy creation and enforcement. Blacklists and whitelists can be created for specific networks and policies may be time and day-of-week based if required. Web content can be filtered by domain or through powerful URL matching expressions. This module is ideal for sites that wish to enforce a restricted view of the web or who wish to prevent access to specific web sites or types of web content.

A sender address blacklist is now available. This list configures sender addresses and domains that the NetBox SMTP server will never accept. This blacklist can be accessed at Configuration > SMTP Server in the NetBox web interface.

Automatic reboots of the NetBox can now be scheduled. This is useful if you have made configuration changes and wish to have them take effect some time in the future (eg. out of business hours). Scheduled reboots can be set at Administration > scheduled reboot in the NetBox web interface.

A new Internet connection type called “None” now exists. This is intended for NetBox configurations that don't have a Internet connection (eg. where the NetBox is acting as an email scanner only).

An internal system used for user authentication was updated to address newly discovered security concerns.

It is now not possible to enter routes that conflicting with other internal or custom routes on the Additional Routes screen.

A fix was made to the virus definition update subsystem to streamline the way updates are done for the Sophos scanning engine.

The NetBox webmail interface has been revamped to provide many new features and improved usability. New features include:

• Composing, reply and forwarding of messages including adding of attachments
• Folders support to allow better organisation of emails
• Sorting of messages on message list screens
• Paging on message list screens to better handle large mailboxes
• Improved HTML message display
• Flagging of messages
• Attachment indication and seen/unseen indication

SMTP traffic relayed through the NetBox is typically not recorded by the Network Monitoring module because this traffic is sent to the NetBox and not through it. To solve this problem, the Network Monitoring module now handles SMTP traffic as a special case and can attribute it to the proper LAN user/IP. Both local and pass-through domains are supported. To enable this feature, go to Network Monitoring > config in the NetBox web interface.

The Scheduled Reboot feature has been extended to allow for power-offs as well.

The NetBox internet connection manager will now automatically modify the MAC address of the ethernet interface when connection attempts repeatedly fail. This allows for quicker reconnection by working around problems with ADSL equipment at the ISP.

The NetBox SMTP access controls at Configuration | SMTP Server | SMTP access control in the web interface now allow configuration of hosts and networks that are trusted. The NetBox will unconditionally accept email from IP ranges configured as trusted. These access controls are applied before the NetBox's builtin access control mechansims and so can be used to override the default behaviour.

The ClamAV virus scanning engine was updated to enhance detection abilities and address security concerns.

The NetBox web proxy was updated to address various security issues. Additionally, adjustments were made to the web proxy error pages to work around display faults in Internet Explorer.

Minor fixes were made to the webmail system to account for unusual message and date encodings.

Another update of the ClamAV virus scanning engine to address various bugs.

A major update of the NetBox IMAP and POP3 server was done to address serious security problems.

The base64 decoding routines of the Email Scanning module have been made more robust so that a wider range of incorrectly encoded message attachments may be decoded.

The Email Scanning Invalid Message Encoding Criteria now has an option to detect messages with payloads that can not be decoded. This allows filtering of such messages. This setting is called "Check for attachment encoding errors" in the Invalid Message Encoding criteria.
