Benefits

• **Choose the storage that you want to use - Object/Block, Cloud/Local, CapEx/OpEx: **With Dovecot Pro you have the choice of cloud or local “in-house” storage. This also results in a shift between OpEx and CapEx. You have the option to use object storage, which comes with many benefits. Its native replication and redundancy capabilities represent an economical and reliable alternative to traditional SAN/NAS storage systems. Regardless of the storage solution you choose, Dovecot Pro delivers high availability access to users’ mail data, even in complex scenarios like shared mailboxes.
• **Make downtime a thing of the past - Built-in and Automated Resilience: **Dovecot Pro is a high-availability, stateless platform. It uses clustering to provide built-in redundancy. The system can intelligently and automatically load-balance traffic, ensuring the health of individual servers. Each component can be shut down for maintenance or upgraded without affecting service availability. It protects against outages, while delivering a system that can grow seamlessly. Open-Xchange also provides enterprise-grade support, which adds an additional level of reliability: 24/7 Platinum Support, for complete peace of mind around the clock.
• **Save money Significant Cost Savings: **Depending on your choice of storage solution, your architectural requirements and your current implementation, Dovecot Pro can save you a little or a lot. The Dovecot Palomar architecture is unmatched anywhere and yields many areas of cost savings. These can become extremely significant when moving from a homegrown, Open-Source solution to a structured and supported Dovecot Pro platform.
• **Ultimate email security - Advanced Security & Protection: **Dovecot Pro is designed to minimize the likelihood and impact of security issues. We ensure security on many levels, such as peer code reviews, static source code analysis, third-party code reviews and a bug bounty program. In addition, Dovecot Pro supports at-rest storage encryption and on-the-wire encryption for all connections to the Dovecot nodes. Dovecot Pro supports a variety of authentication features (OAUTH2, OX Abuse Shield, scriptable Lua authentication) to prevent unauthorized access to the systems.
• **Keep your email system legal with ease Legal Compliance: **With Dovecot Pro, service providers are guaranteed hassle-free compliance with legal requirements through a flexible interception framework. Whenever necessary, it supports the interception of IMAP and POP3 protocol events, LMTP deliveries, appended messages, and more. Legal-interception vendors can be added, and the intercepted data can be exported to local disks or object storage.
• **Let us migrate your users - End-to-End Migration Assistance: **Once the system is fully tested and ready to go, users need to be migrated. A Dovecot Pro license provides access to our migration experts, who have successfully moved tens of millions of mailboxes between services without significant downtime. These experts are available to assist, educate, and plan seamless migrations so that your end-users can be quickly onboarded to your new system.
