Popa3d

Secure, performance, tiny POP3 daemon

the popa3d goals

Is a POP3 daemon by Solar Designer.

Well, the goals themselves are obvious; they’re probably the same for most other POP3 servers as well. It’s their priority that differs. For popa3d, the goals are

  1. Security to the extent that is possible with POP3 at all, of course.
  2. Reliability again, as limited by the mailbox format and the protocol.
  3. RFC compliance slightly relaxed to work with real-world POP3 clients.
  4. Performance limited by the more important goals, above.

This port is installed to be run from inetd, which is sufficient for normal usage. However, it is possible to build a stand-alone version, should you need better performance.
