## Description

dma (DragonFly Mail Agent) is a lightweight MTA for home and office environments. It accepts emails from local mail clients and delivers them locally or to remote destinations via SMTP. It supports TLS/SSL encryption and SMTP authentication for secure remote delivery. Unlike full MTAs such as sendmail or Postfix, dma does not accept incoming connections on port 25, making it suitable for outbound-only mail. It installs via package managers on FreeBSD, Ubuntu, and Arch, or builds from source on Linux and BSD. Configuration uses two files in /etc/dma: auth.conf for SMTP credentials and dma.conf for smarthost, port, aliases, spool directory, and TLS options. Licensed under a BSD-style license, actively maintained since 2011.
