It is used by mail operators, developers, and automation scripts to exercise SMTP, ESMTP, LMTP, TLS, authentication, and message-delivery edge cases. ### Project history The official project page describes Swaks as a featureful, flexible, scriptable, transaction-oriented SMTP test tool written and maintained by John Jetmore. The official versions page lists releases back to 2003, and the GitHub mirror/repository metadata shows the current source repository at jetmore/swaks. ### Adoption history Swaks has broad package-manager coverage because SMTP testing is useful on servers, workstations, CI systems, and mail infrastructure. The input package facts list packages across apk, Homebrew, Debian, Fedora/dnf, MacPorts, Nix, Arch/pacman, Ubuntu, and zypper. ### How it is used The reference documentation emphasizes transactions: choose a recipient and server, test authentication, attach EICAR or GTUBE payloads for mail-filter checks, use LMTP over a Unix socket, or script recipient verification loops. Options can come from a config file, environment variables, or command-line flags, with later sources overriding earlier ones. ### Why package nerds care Swaks is beloved in package-manager culture because it is a single-purpose diagnostic executable with deep protocol knobs and minimal ceremony. It is the sort of tool administrators expect to install quickly during incident response, image building, or integration testing, which explains its presence in many Unix package sets. ### Timeline - 2003: Earliest official release listed on the Swaks versions page. - 2017: GitHub repository created. - 2020: v20201014.0 and v20201024.0 releases appear in the official versions history. - 2024: v20240103.0 released as the latest version listed on the official project page during research. ### Related projects - Swaks is related to SMTP, ESMTP, LMTP, TLS, authentication mechanisms, mail filters, and test payload conventions such as EICAR and GTUBE, all of which appear in its official examples and feature list. ### Sources - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
