    libpop3

    libpop3

    a lightweight ANSI C library for handling POP3 mailboxes

    libpop3 is a very light POP3 library for C. It allows to list, fetch and remove messages from a POP3 mailbox. This library is using the RFC1939 as reference, and uses most basic POP3 commands to provide maximum compatibility across different servers. libpop3 is written in pure ANSI C89 without any external dependencies, thus it can be compiled and used on anything, anywhere. Since it is very light, it is designed to be used as a static library (but you could just as well incorporate its code right into your project).
