[appsuite-announce] Open-Xchange releases Dovecot Anti-Abuse Shield v1.4.0

[Open-Xchange App Suite Maintenance Announcements]

Dear Customers and Partners of Open-Xchange,

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
