Description
Haraka is capable of managing thousands of simultaneous connections and can process an impressive volume of messages each second. Both Haraka and its plugins are developed using asynchronous JavaScript, resulting in exceptional speed and performance. With robust spam protection mechanisms available through its plugins, Haraka serves effectively as a filtering MTA. Additionally, it functions well as a Mail Submission Agent (MSA) on port 587 when utilizing authentication and DKIM signing plugins. Unlike traditional mail servers such as Exchange or Postfix, Haraka is not designed to act as a mail storage solution, Local Delivery Agent (LDA), or an IMAP server like Dovecot or Courier. Instead, it is typically combined with these systems for enhanced functionality. The built-in outbound mail delivery engine of Haraka is scalable, ensuring efficient processing of messages marked for relaying through authentication plugins, which are automatically queued for delivery. Furthermore, Haraka's plugin framework allows for easy extensions, making it a complementary option for traditional MTAs that may lack adequate filtering capabilities, thus enhancing the overall email handling process. This modular approach provides flexibility, enabling users to tailor their email solutions according to specific needs.

KumoMTA is an open source mail transfer agent and email infrastructure platform for enterprises, MailOps teams, and high-volume senders. The platform is built to provide the control, scalability, transparency, and continuity that organizations need when email delivery is central to their business. KumoMTA is positioned as an alternative to commercially licensed MTA providers that may create pricing shocks, renewal risk, vendor dependency, or black-box infrastructure limitations. The platform can deliver tens of millions of messages per hour on a single instance and is designed to support large-scale sending without data loss. Its open source model gives teams direct access to the code and more authority over deployment, operations, and long-term infrastructure decisions. KumoMTA also emphasizes performance, resilience, cost predictability, fairness, and transparent stewardship. The community includes developers, security researchers, and enterprises that help audit code, identify vulnerabilities, and improve the platform over time. KumoMTA provides extensive documentation, a community forum, GitHub repository, migration resources, and support options for teams moving from other MTA platforms. By combining open source email infrastructure, high-volume performance, operational control, community development, documentation, and enterprise support, KumoMTA helps organizations invest in their own email infrastructure with greater confidence.
