MDaemon Messaging Server is a Windows-based email and groupware server developed by Alt-N Technologies, based in Grapevine, Texas.

MDaemon's features include a built-in spam filter with Heuristic and Bayesian analysis, SSL and TLS encryption, public and shared folder support, mailing lists, web-based email client (WorldClient), support for sharing of groupware data (calendar, contacts, tasks & notes), over-the-air synchronization of mobile devices via ActiveSync, CalDAV, BlackBerry Internet Service, and an optional BlackBerry Enterprise Server (BES) plug-in.

MDaemon's main configuration files are stored in the MDaemon/App directory and email is stored in a flat-file structure within the MDaemon/Users directory.

In the mid 1990s, Arvel Hathcock began writing MDaemon. Hathcock began writing software at the age of 14 on a TRS-80 model MC-10 that his father bought him. After developing bulletin board software for several companies, he joined Mailing List Systems Corporation. Hathcock became frustrated at the expense of the available email software and decided to write his own. In 1996 he founded Alt-N Technologies to produce and sell his email server, MDaemon.

MDaemon includes a web-based email client (WorldClient) for browser-based access to email,birthday, calendars, contacts, documents, tasks and notes. Documents can be attached to messages or placed in a shared document repository via drag & drop. Custom access rights can be granted to public and shared folders for collaboration purposes. The integrated chat sidebar can be used to chat with other MDaemon users.
