The AUTHORS file says msmtp was mostly written by Lambers and that much of its code is shared with mpop. Its manual describes the default mode: read a message from standard input and send it to a configured SMTP server, while keeping command-line options and exit codes compatible with sendmail. ### Project history The project grew into a focused replacement for the sending side of a local mail transfer agent. Its configuration organizes SMTP servers as accounts with host, authentication, TLS, and related settings, and the manual documents TLS, multiple authentication mechanisms, delivery status notifications, PIPELINING, server-information mode, Remote Message Queue Starting, and the minimal SMTP server msmtpd. ### How it is used msmtp's adoption niche is the modular command-line mail stack. It is commonly paired with MUAs rather than acting as a full mail server: the Debian wiki names Mutt and Emacs as examples, and the manual includes examples for Mutt and traditional mail commands. Package managers often provide it as both the `msmtp` executable and a sendmail-compatible MTA alternative for scripts, cron jobs, and small systems that only need outbound SMTP relay. ### 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.
