MDaemon is equipped with an Extensible Messaging and Presence Protocol (XMPP) server, sometimes called a Jabber server. This allows your users to send and receive instant messages using MDaemon Instant Messenger and third-party XMPP clients, such as Pidgin, Gajim, Swift and many others. Clients are available for most operating systems and mobile device platforms.

The XMPP server is installed as a Windows service, and the default server ports are 5222 (SSL via STARTTLS) and 5223 (dedicated SSL). The XMPP server will use MDaemon's SSL configuration if it is enabled in MDaemon. Also, some XMPP clients use DNS SRV records for auto-discover of host names. Please refer to for more information.

Users sign-in through their chosen XMPP client using their email address and password. Some clients, however, require the email address to be split into separate components for signing in. For example, instead of "," some clients require you to use "frank" as the Login/Username and "" as the Domain.

For multi-user/group chat service, clients typically display this as "rooms" or "conferences." When you want to start a group chat session, create a room/conference (giving it a name) and then invite the other users to that room. Most clients don't require you to enter a server location for the conference; you only need to enter a name for it. When you are required to do so, however, use "conference.<your domain>" as the location (e.g. A few clients require you to enter the name and location together in the form: "room@conference.<your domain>" (e.g.

Some clients (such as Pidgin), support the user search service, allowing you to search the server for users by name or email address, which makes adding contacts much easier. Usually you will not have to provide a search location, but if asked to do so, use "search.<your domain>" (e.g. When searching, the % symbol can be used as a wildcard. Therefore you could use "" in the email address field to display a list of all users with an email address ending in ""
