    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.
