The GNU POP3 daemon is a small, fast, and efficient POP3 server. It is written with performance and RFC compliance in mind, and supports virtual domains (i.e. several domain names on the same server).
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
Several bugfixes for various clients (Netscape 3.x, Windows telnet),
bugfix for random deletion problem, idle timeout command line
option, and command line option for listening on different ports.
Because of a thus-far unreported bug that may cause messages to
be erroneously deleted, upgrading to this release is strongly
recommended.
