OpenSMTPD VS imagecli

• 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

• 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.

• Simple CLI interface
  image-cli offers a straightforward command-line interface that lets users perform common image operations like resizing, converting formats, and compressing without writing code, making it accessible for quick tasks and scripting.
• Built on Sharp
  Under the hood it leverages the Sharp library, which is known for high performance and low memory usage when processing images, so users benefit from fast conversions and resizing even for large batches.
• Multiple format support
  The tool supports converting between popular image formats such as JPEG, PNG, WebP, and AVIF, giving developers flexibility to optimize images for web or other platforms without needing separate tools.
• Batch processing
  image-cli can process multiple files or entire directories in one command, which is useful for automating image optimization pipelines in build scripts or CI/CD workflows.
• Lightweight and easy to install
  As an npm package, it can be installed quickly via npm or yarn and used directly with npx, requiring minimal setup compared to more complex image processing suites.

Possible disadvantages

• Limited advanced features
  Compared to full-featured image editing suites, image-cli offers a relatively narrow set of operations (resize, convert, compress) and lacks more advanced manipulations like layers, filters, or complex transformations.
• Dependency on Node.js ecosystem
  Since it's an npm-based CLI, users need Node.js and npm installed, which adds an extra dependency for those who just want a standalone binary without a JavaScript runtime.
• Documentation gaps
  Being a smaller, less mainstream project, the documentation may be sparse or lack detailed examples for edge cases, making it harder for new users to discover all available options or troubleshoot issues.
• Maintenance and community support
  As a side project by an individual maintainer (egoist), the tool may receive infrequent updates or slower bug fixes compared to more actively maintained, enterprise-backed image processing tools.
• Limited error handling and feedback
  Some users report that error messages when processing fails (e.g., unsupported formats or corrupted files) can be unclear, making debugging batch operations more time-consuming.

• 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... Source: over 3 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 / over 5 years ago
