important Important:
On February 15, 2016, an update was automatically distributed to all existing version 3.1.6 users to fix several vulnerabilities found in the Remote Admin interface. At the same time, the installation packages were updated so that all new installations have the security patches available from the start. We strongly recommend that all pre-3.1.6 installations be upgraded to the current version.


Overview

The new Bitdefender Security for Mail Servers 3.1.6 Linux packages include all product updates delivered since the previous release, as well as a number of other improvements and bug fixes.

New Features and Improvements

  • Due to large number of spam messages having DKIM signatures, Bitdefender Security for Mail Servers is now configured to ignore the signature and modify the email subject accordingly. The setting can be disabled as follows:
    • In the Remote Admin console, from Policies > [Group] > Antispam > Configure, clear the Ignore the signature option.
    • From command line, by running the following commands:
      # ./bdsafe group conf default antispam ignoresignature N
      # ./bdsafe reload bdmaild
  • Added more user-friendly update status messages in the Remote Admin console, Maintenance section.

Resolved Issues

  • When using multiple group policies, changing content filtering rule settings in a policy resulted in changes being replicated across all policies. The issue is now fixed.
  • Fixed an issue with attachment name filtering not working for a particular file header format.
  • Fixed an issue with notifications not being sent to original recipients.

Known Issues

License activation and periodic validation does not work with ISA proxy using basic or NTLM authentication.

Upgrade Guidelines

Existing customers can easily upgrade to version 3.1.7 by running the new installation package over their existing installation. The upgrade will preserve the current product settings.

If your installation is running on a legacy machine, before upgrading, make sure the minimum hardware requirements are met:

  • Minimum RAM memory: 512 MB
  • Minimum free hard disk space: 500 MB (note that quarantine and logs will require additional space)

Starting with version 3.1.4, Bitdefender Security for Mail Servers requires Internet connectivity, either directly or through an HTTP proxy, for license activation and periodic validation. However, the product can work without Internet connection for several days.

  1. Download the installation package suitable for your environment: Packages are named according to the following convention:
    BitDefender-Security-Mail-linux-{arch}.{pkg}.run
    where {arch} substitutes for i586 or amd64 and {pkg} substitutes for the package type (rpm, deb, ipk).
  2. Run the package with root privileges using the sh command.
    e.g.: #sh BitDefender-Security-Mail-linux-amd64.rpm.run
note Note:
