The History of KumoMTA

KumoMTA is an open source Message Transfer Agent (MTA) designed to provide high performance outbound email functionality.

The KumoMTA project was founded by a group of email industry veterans with decades of experience building and managing high-performance On-Prem MTAs and is supported by a community of some of the largest senders in the world. While paying attention to the lessons of history, KumoMTA was designed from the ground up with new tech as opposed to modifying something that already existed. We specifically avoided making a modification of Postfix or Exim or some other existing MTA and instead wrote entirely new code in Rust.

What is a "Kumo"?

So how did we come up with the name KumoMTA? We set out to build a cloud deployable on-premises MTA that was flexible enough to install both on bare metal and in a public or private cloud. Kumo means cloud in Japanese, so "KumoMTA" is a Cloud MTA.

Why Open Source?

High volume commercial MTAs tend to have closed source code and steep license fees. Neither of these are particularly bad as long as the software is maintained and is flexible enough to modify. However, the kind of people who typically install very complex high-volume MTAs usually want to modify it or integrate it into other systems. Providing an open source option allows people to modify the code as needed, and contribute modifications easily to the community. The email community is full of very smart, creative people who now have an avenue to contribute to a wider community project.

  • Visual comparison of options
    The tool provides a visual representation of how different options compare against each other across various criteria, making it easier to see which option comes out ahead overall.

Possible disadvantages of SimpleX

  • Limited advanced features
    SimpleX focuses on simplicity, which means it may lack more sophisticated decision analysis features such as sensitivity analysis, probability weighting, or Monte Carlo simulations that more advanced tools offer.
  • Low visibility and community
    SimpleX is a relatively niche tool with a small user base, which means limited community support, fewer tutorials, and less peer feedback compared to more established decision-making platforms.
  • Potential oversimplification
    For complex decisions involving many interdependent variables, the simplified framework may not adequately capture nuances, dependencies, or non-linear relationships between criteria.
  • Limited collaboration features
    The tool may lack robust collaboration capabilities for team-based decision-making, such as real-time co-editing, role-based access, or voting mechanisms for group consensus.
  • No offline functionality
    Being a web-based tool, SimpleX requires an internet connection to function, which can be a limitation in situations where connectivity is unreliable or unavailable.
