qmail features and specs

• Security
  qmail was designed with security in mind, and its architecture has been praised for its robust security features. It avoids common vulnerabilities found in other mail transfer agents by running most of its components as non-root, thus minimizing the risk of privilege escalation.
• Performance
  qmail is known for its high performance and efficiency. It uses a modular design that allows it to handle large volumes of email with relatively low resource consumption.
• Reliability
  qmail's design prioritizes reliability. It is built to work in a predictable, stable manner, making it a trusted solution for handling mail.
• Modular Design
  qmail is composed of modular components, which makes it easier to troubleshoot and manage individual parts of the system without affecting the entire service.
• Maildir Support
  qmail natively supports Maildir, which is a more efficient and safer storage format compared to mbox, as it stores each message as a separate file, helping to prevent corruption issues.

Possible disadvantages of qmail

• Lack of Recent Updates
  qmail has not been actively maintained for many years, leading to concerns about missing out on modern features and improvements.
• Complex Configuration
  The configuration and management of qmail can be complex compared to other modern mail transfer agents, which can make it challenging for new users to set up and maintain.
• Limited Features
  qmail lacks many features that are now standard in other MTAs, such as built-in spam filtering and IPv6 support. Some functionalities require external patches or add-ons to implement.
• Licensing Restrictions
  The software's licensing under the terms of the qmail license restricts modification and redistribution, which might be a concern for some users who want to customize or distribute modified versions.
• Community Support
  Because qmail is no longer actively developed, the community support and documentation can be lacking compared to more widely adopted and actively maintained alternatives.
