[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 v1.4.1.

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.

The main focus is a fix for mapped v4 addresses inside v6 addresses, for customers accepting logins on IPv6.
