About mpop

mpop is a POP3 client: it retrieves mail from POP3 mailboxes.

• Support for multiple accounts
• Header based mail filtering: filter junk mail before downloading it
• Delivery to mbox files, maildir folders, or a mail delivery agent (MDA)
• TLS support including client certificates
• Many authentication methods
• Support for Internationalized Domain Names (IDN)
• Fast POP3 implementation using command pipelining
• SOCKS proxy support

mpop runs on a wide variety of platforms. It needs little more than an ANSI C compiler and Berkeley-style sockets. It does not require any additional libraries, but it can use the following to enhance its feature set:

• GnuTLS
  The GnuTLS library provides TLS support. Alternatively, libtls from the LibreSSL project can be used.
• GNU SASL
  Using the GNU SASL library adds support for some additional authentication methods. You only need it for SCRAM-SHA-* and GSSAPI.
• GNU libidn2
  On modern Linux systems with recent glibc and GnuTLS libraries, mpop has automatic support for Internationalized Domain Names (IDN). On other systems, IDN support is available via libidn2.
