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