In addition, user level features also include:

  • Individual Whitelists and Blacklists
  • Individual Message Logs
  • Individual Quarantine Management

Automatic Domain and User Creation

Domains can be added automatically from verified and trusted email servers enabling practically hands-free maintenance of the domain and user base.

Individual Quarantine Emails

Users can opt to receive periodic summary emails of any messages sent to them that have been trapped in the quarantine. A one-click, Web based system enables users to quickly review, and then accept or reject mesaages from within their mail client at the touch of a button.

Automatic Periodic Backup

Periodic backups can be scheduled to prevent loss of the gateway data, including the logs and graphical reports. The system can keep all backups or only a specified number of recent backups. Message files, if available, are kept in the backup as well.

Message Management

By viewing the message log, an administrator can see a list of all messages processed, along with information about the status of each message delivered, quarantined, rejected and why. This information can also be used for fine-tuning the filters.

Defense Layer Customization™

Simple up and down arrows within the easy-to-use interface enable an administrator to change the order in which a specific security rule will execute when analyzing incoming or outgoing email traffic. This technique can result in faster processing of email by allowing the rejection or quarantine of messages at the earliest point during processing.
