The project news says the first public mpop release, 0.1.0, was published on 2004-06-08, eleven months after msmtp, and the AUTHORS file says much of the code is shared with msmtp. The manual and project pages describe the package as a GPL mail retriever that can poll one or more POP3 mailboxes, skip mail already delivered by tracking UIDLs, filter headers before downloading a message, and deliver through an MDA, to maildir, or to mbox. ### Project history Its history is mostly a steady hardening of a Unix mail pipeline tool rather than a move into a larger mail suite. The 1.4.0 stable series in 2018 discouraged OpenSSL in favor of GnuTLS, moved IDN support to libidn2, disabled GNU SASL by default, and dropped obsolete systems and weak authentication choices. Later releases added OAuth-oriented authentication support: OAUTHBEARER in 2019, XOAUTH2 in 2020, libtls support in 2020, SCRAM-SHA-256 via GNU SASL in 2021, and a minimal mpopd POP3 server in 2021 for mail clients that cannot read local mail stores directly. ### How it is used mpop's niche is narrower and more scriptable than fetchmail. Its own documentation compares it with fetchmail by emphasizing no daemon mode, use from cron, no IMAP or multidrop support, faster POP3 command pipelining, direct maildir and mbox delivery, and header filtering that can reject junk before a full message download. In practice it is used by people who want local control over incoming mail with normal Unix tools such as procmail, SpamAssassin, cron, netrc, and local mailbox formats rather than a GUI mail client doing retrieval itself. ### Sources - - - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
