mpop

mpop project is a small and fast POP3 client with header based mail filtering capabilities.

mpop is released under the GPL with the additional exemption that compiling, linking, and/or using OpenSSL is allowed.

Requirements:

� If you want TLS/SSL support, you need either GnuTLS (>=1.2.0) or OpenSSL (>=0.9.6).
� You can optionally use GNU SASL if you need more authentication methods than USER/PASS, APOP, PLAIN, LOGIN, and CRAM-MD5; for example GSSAPI, DIGEST-MD5 or NTLM.
� On systems other than GNU/Linux you need GNU gettext for native language support.

Features:

• Header based mail filtering: filter junk mail before downloading it
• Delivery to mbox files, maildir folders or a mail delivery agent (MDA)
• Very fast POP3 implementation, using command pipelining
• Authentication methods USER/PASS, APOP, PLAIN, LOGIN and CRAM-MD5 (and GSSAPI, DIGEST-MD5, and NTLM when GNU SASL is used)
• TLS encrypted connections (including server certificate verification and the possibility to send a client certificate)
• IPv6 support
• support for multiple accounts

What is new in this release:

• This version fixes a minor problem with a network-related error message.

What is new in version 1.0.26:

• This version fixes a problem with configurations that use OpenSSL and at the same time do not use GNU SASL. (If you use a different configuration, there's no reason to upgrade.)

What is new in version 1.0.25:

• This release fixes a few problems, and marks DIGEST-MD5 authentication as deprecated (see RFC 6331).

What is new in version 1.0.23:

• This release fixes SCRAM-SHA-1 authentication via GNU SASL.
• If you use a version of mpop that supports SCRAM-SHA-1 authentication via libgsasl (see the output of mpop --version), then an update is recommended.

What is new in version 1.0.22:

• This release adds a passwordeval command that allows to set the password to the output of a program invocation.

What is new in version 1.0.21:

• This minor update mainly fixes build problems with newer OpenSSL versions and with disabled TLS/SSL support.

What is new in version 1.0.20:

• This release adds support for authentication mechanism SCRAM-SHA-1 via GNU SASL. The new command tls_fingerprint allows one to trust one particular TLS certificate, in case tls_trust_file cannot be used for some reason. The new script mpop-gnome-tool.py manages Gnome Keyring passwords for mpop.

What is new in version 1.0.18:

• This release adds support for delivery to Exchange pickup directories and fixes some minor problems.

What is new in version 1.0.17:

• Update gnulib to 2009-04-11.
• Update gnulib to 2009-03-07. Remove gnulib modules fseek/fseeko/lseek because they cause errors on MinGW: files opened with "r+" cannot be written to. Provide our own fseeko instead if it does not exist; see configure.ac.
• Improve test for non-existing UIDLS file.
• Fix an invalid memory access in pop3_retr().
• Document that maildir delivery requires a file system that supports hard links.
• Use more gnulib modules to remove more W32 workarounds from the source.
• Add missing gnulib module strerror for meaningful error messages on W32.
