This .NET class allows to administrate the MDaemon Mail server, like creating domains and user accounts.

The MDaemon Mail Server

Do you need a mail server? Do you own Web Hosting and want to add Mail support for your clients?

You could install a Microsoft Exchange Server, but there is much better solution: I recommend MDaemon from alt-n technologies.

This mail server offers the same functionality, is cheaper, occupies less RAM and is much much easier to configure. The user can chose between several web themes - one of them looks exactly like Outlook Web Access. You can fully control the server's functionality from your own administration application written in C++ or .NET.



The MDaemon API

If you decide to add new mail domains and new user accounts 100% automatically, this is very easy.

  • In C++ you use the MDUser.dll which offers access to the entire server functionality .
  • In .NET you can use the MDUserCOM.dll which offers access to the majority of the funcionality, but not all.

I asked the alt-n technologies support why there are some function missing in the COM DLL like creating new domains for example. They never answered me.

The MDaemonController

So I wrote the MDaemonController .NET project. It is a managed C++ DLL that can be used in C# and VB .NET projects. It offers access to ALL API functions that are needed to create and manipulate domains and user accounts.


Example to create a new domain in C#:

using MDaemon;
cDomain i_Domain = new cDomain();
i_Domain.DomainName = "";
i_Domain.FQDN       = "";
i_Domain.IP         = "";
i_Domain.MaxUsers   = 10000;

Example to create a new user in C#:

using MDaemon;
cUser i_User = new cUser();
i_User.FullName  = "Johnny Walker";
i_User.Mailbox   = "jwalker";
i_User.Password  = "123ABC";
i_User.Domain    = "";
i_User.MailDir   = "C:\\emails\\jwalker";
i_User.WebConfig = cUser.eWebConfig.ACCESS_WORLDCLIENT | 
    cUser.eWebConfig.EDIT_PASSWORD | cUser.eWebConfig.IS_ADMIN;
  • You can create domains, create user accounts and modify existing domains and users and search users.
  • You can enumerate all domains and all users.
  • The classes cUser and cDomain have various properties which are automatically filled with the default server values when a new class is created. You can work with these defaults or modify them.
  • All C++ constants have been converted into handy .NET enumerations.
  • The classes have a clean error handling that translates the C++ error codes into human readable error messages which are thrown as exceptions.

The code uses the following C++ functions:
MD_InitDomainInfo, MD_FreeDomain, MD_WriteDomain, MD_DeleteDomain, MD_GetDomainCount, MD_GetDomainNames, MD_VerifyDomainInfo


MD_InitUserInfo, MD_GetFree, MD_VerifyUserInfo, MD_AddUser, MD_GetByEmail, MD_GetUserInfo, MD_SetUserInfo, MD_DeleteUser, MD_UserExists, MD_FindFirst, MD_GetEmail, MD_FindNext, MD_FindClose

More Functionality

If you need programmatical acces to Mailing Lists, Message Handling, Rule Management or Gateway Functions then add the MDUserCOM.dll to your .NET project that contains these functionalities.

The Demo Project

This DLL comes with a demo application that shows how to use the DLL. It is ultra easy so I will not explain much here.

Have a look into the code! The comments in the C++ code explain the functions. The C# demo shows how to use them.
