Developers, self-hosters and small teams who want to run their own mail server and newsletters
About lfr
lfr is self-hosted mail-server and newsletter software packaged as a single Go binary for Linux and macOS servers. It lets developers, self-hosters, and small teams host mailboxes for their domains, manage aliases and forwarding, search and reply to messages, and configure domain mail records. Newsletter tools support double-opt-in signup lists, Markdown-based issues, hosted archives and signup websites, one-click unsubscribe, bounce and complaint handling, and delivery through a configurable SMTP relay when direct sending is unavailable. The command-line interface runs locally or over SSH, with setup and diagnostic commands for server, DNS, and mail delivery tasks. lfr is distributed under the MIT license; the software itself is free, while users arrange and pay for their own server and any optional relay service.
