[Open-Xchange Server Edition Maintenance Announcements]

Dear Customers of Open-Xchange,

Open-Xchange is pleased to announce the release of OX Abuse Shield v3.0.0.

OX Abuse Shield provides abuse-prevention for Web Applications (including Webmail), POP, and IMAP. It is integrated with both OX App Suite and Dovecot Pro to prevent login and authentication abuse as well as protecting against brute-force attacks.

The goal of OX Abuse Shield is to detect brute forcing of passwords across many servers, services and instances, as well as enforce policy for authentication and authorization. In order to support the real world, brute force detection policy can be tailored to deal with "bulk, but legitimate" users of your service, as well as botnet-wide slow-scans of passwords.
