OpenSMTPD features and specs

  • Simplicity
    OpenSMTPD is designed to be simple and straightforward, which makes it easier to configure and manage compared to other mail transfer agents. Its configuration syntax is clean and readable.
  • Security-focused
    One of the main goals of OpenSMTPD is to provide a secure mail transfer agent. It is developed by the OpenBSD team, which is known for its emphasis on security.
  • Lightweight
    OpenSMTPD is a lightweight solution, using minimal system resources, making it suitable for systems with lower hardware capabilities or for those looking to optimize performance.
  • Integration with OpenBSD
    As a project developed by the OpenBSD team, OpenSMTPD integrates well with OpenBSD, taking advantage of the system's security features and optimizations.
  • Active Community
    OpenSMTPD has an active development community, which provides timely updates, patches, and support, helping to keep the software secure and reliable.

Possible disadvantages of OpenSMTPD

  • Feature Limitation
    Compared to more established mail servers like Postfix or Exim, OpenSMTPD may lack some advanced features or integrations that larger enterprises might require.
  • Limited Documentation
    The documentation for OpenSMTPD, while improving, is not as comprehensive as that for more widely-used MTAs, which can create a steeper learning curve for new administrators.
  • Less Third-Party Support
    Due to its lesser adoption compared to other MTAs, there might be fewer third-party tools, plugins, and resources available for extending OpenSMTPD's capabilities.
  • Platform Specific Optimization
    While its integration with OpenBSD is a strength, it may not be as optimized for other operating systems, possibly leading to a less efficient experience outside the BSD ecosystem.
  • Community-Centric Development
    Being a smaller, community-driven project, OpenSMTPD may not offer the same level of support or development resources as more commercially backed mail server solutions.

  • Has anyone setup a Linux based internal only smtp relay?
    I've had something of the same experience with Postfix, u/0x29aNull. Check out OpenSMTPD. It is lightweight and standards compliant. I know that there are packages for Debian and Alpine Linux. There may also be ones for Fedora/RHEL derivatives. I use it in my environment on OpenBSD. Source: about 2 years ago
  • DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD
    When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / almost 4 years ago
