Dynamic scalability and efficient hardware utilization
With a marketshare of 76% of installed email backends, customers trust the performance of Dovecot Pro. Efficient hardware utilization and advanced monitoring tools for statistics and administration reduce ownership costs and save time and maintenance costs. In addition, Dovecot Pro scales up and out to hundreds of servers and millions of users and multiple physical sites. Its stateless native architecture offers maximum flexibility as each major component can be deployed on its own dedicated node.
Industry-leading support for all email standards
Dovecot Pro provides industry-leading support for all email standards necessary to provide both Mail Delivery Agent functionality (via LMTP and Sieve), and to facilitate mail retrieval by mail clients (via IMAP and POP3). Dovecot Pro not only provides efficient operation of these protocols, utilizing caching and indexing, but it also supports advanced extensions which enable improved user experiences and decreased resource usage when implemented.
Security and Protection
Dovecot Pro has been designed from the beginning with security in mind, utilizing industry-standard practices, such as privilege separation, to ensure that customers' data safety is an inherent feature of the platform. Dovecot Pro supports full encryption between all services, natively supports email data encryption at-rest, and allows use of modern authentication methods, such as OAUTH. Dovecot Pro is tightly integrated with OX Abuse Shield, addressing the problem of login abuse through all publicly available protocols.
Professional Services and Support
Dovecot professionals provide up to 24/7 support based on clearly defined SLA's. To optimize performance, the same experienced specialists also handle design, architecture and customization. Open-Xchange and Dovecot experts can also help ensure a smooth migration from existing deployments. Using the Dovecot Pro Migration Framework enables massive email migrations involving millions of mailboxes.
OX App Suite & Dovecot Pro
Both Dovecot Pro and OX App Suite are strong on their own, but even better together. Various innovative OX App Suite features and functions are based on Dovecot Pro, like push notifications, unique advertising options, automatically tabbed inbox, global attachment view, unified quota, shared mailboxes, automatic calendar processing, and virtual folders (patent US9628428). OX App Suite and Dovecot Pro have a proven track record, servicing tens of millions of mailboxes worldwide as well as being the core components of OX Cloud.

Why?
Although the Dovecot 2.0 director-based architecture has served us well, it has reached the end of its useful life. Customer/operator feedback from the last 10 years of Dovecot Pro has identified areas where a new architecture can better solve issues or take advantage of modern standards.
What?
The new platform is a stateless, scalable. highly available, two-layer architecture that is natively designed to run in both bare-metal or cloud environments. it provides integrated user/group management, maintenance automation, built-in health-checking, improved resource utilization, and is exclusive to Dovecot Pro.
