Description

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.

Description

LISTSERV is an email list management system that L-Soft International has created. LISTSERV is available as a hosted service or in-house software. It allows users to manage thousands to millions of email subscribers from one central interface. LISTSERV lists allow subscribers to be organized under one central email address. This eliminates the need to remember subscriber information each time you send an email. Send your message to the list address and it will be sent to all subscribers. You can create one-way mailing lists for alerts, newsletters, or two-way discussion groups for collaboration between members of your organization. Subscribers can create an account through the LISTSERV web interface to manage their subscription settings, view past mailings, and send email to two-way discussions groups. Database connectivity, LDAP integration and automatic bounce handling are some of the features. LISTSERV can work for any organization, regardless of its size or structure.
