// Desciption :         
//	The COXSendMail class is designed to send Mail from Windows NT service applications
//	like the Microsoft IIS server. The class has an extremely simple interface which
//	enables you to send mail with only 3 function calls.
//	The COXSendMail class is based on our MFC framework for extended MAPI (through
//	OLE Messaging). This framework provides 14 powerful classes which allow you to add
//	quickly and easily the ability to send and receive mail messages to your MFC application.
//	It also enables easy interaction with folders and address books. You can create
//	programmable messaging objects. The functionality of these objects can be used to build
//	workflow automation solutions.
//	You can add different kind of recipients (CC, BCC, distribution lists) and attachments
//	(binary, ole-objects) and send it to a MAPI compatible mail system (Exchange, Microsoft
//	Mail, Internet Mail, ...).
//   

// Remark:
//	If your NT service application logs on with a specific user account you must provide an
//	additional privilege for this account: the user-right "Restore Files and Directories" must
//	be granted. If the service uses the system account you have to impersonate a specific
//	user account if you send a message. For example, if you use the Microsoft IIS to call
//	your ISAPI extensions, the IIS will impersonate the anonymous WWW-account ‘USR_COMPUTER_NAME’
//	before calling your extension DLL. 
//	You have to provide a suitable Profile for that user account. If MAPI logs on to a store or
//	transport provider it uses a MAPI profile which defines the providers to use.
//	Instantiate a COXSendMail object and call the Logon() function with the profile name and
//	password as parameters. Call the CreateMessage() function and add your recipients and attachments
//	with the AddRecipient() and AddAttachment() functions. Finally call the SendMessage() function
//	and you are done.
//
//	*** There are two compile version of this class. One that uses our OXMapi framework (don't define 
//		the OX_MAPI_DIRECT switch. And one that uses extended MAPI direct (use the #define OX_MAPI_DIRECT 
//		switch.
