    Open-Xchange releases Dovecot Anti-Abuse Shield v1.4.0

    Open-Xchange is pleased to announce the release of Dovecot Anti-Abuse Shield v1.4.0.

    Dovecot Anti-Abuse Shield is included with Dovecot Pro and works with both Dovecot Pro and OX App Suite as a component to protect against login/authentication abuse.

    Anti-Abuse Shield runs on a cluster of servers, and integrates with OX App Suite and Dovecot to detect abuse, brute force attacks and also to enforce common authentication/authorization policies across the platform.

    Please note: Dovecot Anti-Abuse Shield is only available for customers who have a valid Dovecot Pro license and Dovecot Pro v2.2.27.1 onwards.

    New Features include:
    • The base DAAS package ships with a simple policy to handle brute-forcing protection. This is now supplemented with a separate package providing a comprehensive anti-abuse policy, with easy configuration, containing over 16 different policies including restrictions based on GeoIP, and user/IP whitelisting.
    • Support for GeoIP based on City and ISP databases
    • Support for reloading GeoIP databases without restarting DAAS
    • Blacklisting based on CIDR ranges not just individual IP addresses
