We are pleased to announce the release of Warden Anti-spam and Virus Protection 4.0 under General Availability. This is a major release and all users are encouraged to upgrade. This release has passed Plesk certification and is now available in the Plesk extension directory.
Spam Kill Support
We've added new receive spam and spam kill level options to the tag and move spam filter actions on the policy pages. When receive spam is set to no it will enable the spam kill level where a user can set a spam level to reject mail. Mail will be classified as spammy as potential spam when below the spam kill level or spam when the spam kill level is reached rejecting the mail. The spam kill level rejection happens at the SMTP level before Postfix accepts the mail so the senders mail server will bounce back the message informing the sender. Spam kill level has the additional benefit that email blacklisted under Settings -> Policy Blacklist will be rejected instead of marked as spam. See here for more information.
Unchecked Quarantine Support
We've added support for quarantining unchecked email for even better security. Unchecked mail is when the antivirus cannot scan a message in situations like the anti-virus daemon being down or if the mail contains a password-protected archive. Hackers try to bypass anti-virus scans by sending malware to users using password-protected archives. See here for more information.
Content Statistics Reports
We've added new content statistics incoming and outgoing reports. These reports give you a nice high level overview for what type of content is coming in and out of the server. They will be displayed by default on the dashboard. Press the reset button on the dashboard to view them.
Date Range Search Fields
We've added new date range search fields to the message log, quarantine, queue, and action pages. This makes it easy to search within a specified time frame.
