About

The Courier mail transfer agent (MTA) is an integrated mail/groupware server based on open commodity protocols, such as ESMTP, IMAP, POP3, LDAP, SSL, and HTTP. Courier provides ESMTP, IMAP, POP3, webmail, and mailing list services within a single, consistent, framework. Individual components can be enabled or disabled at will. The Courier mail server now implements basic web-based calendaring and scheduling services integrated in the webmail module. Advanced groupware calendaring services will follow soon. The Courier mail server's source code should compile on most POSIX-based operating systems based on Linux, and BSD-derived kernels. The Courier mail server should also compile on Solaris and AIX, with some help from Sun's or IBM's freeware add-on tools for their respective operating systems. The Courier mail server evolved out of several related projects, that merged together (more on that later). The Courier mail server implements SMTP extensions for mailing list management.

About

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.
