I think this should have been assigned to MHU and not me (MRU)...

IHMO, considering 'Component: framework', it should have been MBA.
Reassigning to component owner...

TM->SW: As discussed, this one is more a macro-problem than a
framework issue. So please have a look ! Thanks !

I just installed OO.o 641d on win2000 and had no problems calling the
method 'sendSimpleMailMessage'.

The following code was used:
<start of code snippet>		XInterface oObj = null;
        XInterface part = null;

		// creation of testobject here
		// first we write what we are intend to do to log file
		log.println( "creating a test com.sun.star.system.SimpleSystemMail" );
        try {
            Object smplMail = Factory.createInstance(
                                       
"com.sun.star.system.SimpleSystemMail");
            oObj = (XInterface) smplMail;
        } catch (com.sun.star.uno.Exception e) {
            e.printStackTrace();
        }
        
        System.out.println("Result for
com.sun.star.system.SimpleSystemMail");
        System.out.println("Name: "+util.utils.getImplName(oObj));
        dbg.printInterfaces(oObj);
        
        System.out.println("Getting the XSimpleMailClientSupplier");
        XSimpleMailClientSupplier smcs = (XSimpleMailClientSupplier) 
               
UnoRuntime.queryInterface(XSimpleMailClientSupplier.class, oObj);
        
        System.out.println("Getting the XSimpleMailClient");
        XSimpleMailClient client = smcs.querySimpleMailClient();
        
        System.out.println("Creating XSimpleMailMessage");
        XSimpleMailMessage msg = client.createSimpleMailMessage();
        
        System.out.println("filling some fields");
        msg.setRecipient("sw@openoffice.org");
        msg.setSubject("Just a test for issuzilla id 3764");
        
        System.out.println("sending message");
        try {
            client.sendSimpleMailMessage(msg,0);
        } catch (Exception e) {
            e.printStackTrace();
        }
<end of code snippet>

Afterwards an outlook-window is opened wherein I can create my message
and parallel I'm able to work with the office.        

Seems it also works for vghost@openoffice.org now => closed
