| Qpopper is the most widely-used server for the POP3 protocol. This allows users to access their mail using any POP3 client. Qpopper supports the latest standards, and includes a large number of optional features. Qpopper is normally used with standard UNIX mail transfer and delivery agents such as sendmail or smail. This server is fully compliant with RFC 1939 (which defines the POP protocol) and RFC 2449 (which defines the POP extension mechanism), and works with all known POP3 clients. Qpopper also supports Kerberos V4 if enabled. |
