DragonFly Mail Agent, a small MTA for local/outbound mail

The DragonFly Mail Agent is a small Mail Transport Agent MTA, designed for home and office use. It accepts e-mail messages from locally installed Mail User Agents MUA and delivers the messages either locally or to a remote destination. Remote delivery includes several features like TLS/SSL support and SMTP authentication, but not MX record lookups. Therefore, dma is currently not suitable for direct remote delivery. However, it works very well for handling local mail plus secure mail submission to a remote smarthost e.g. for travelling mobile computers.

Since dma is not intended as a replacement for real, big MTAs like sendmail8 or postfix1, it does not listen on port 25 for incoming connections.
