Custom MTM questions

Hello,

I have a few questions regarding creating a custom MTM. Would someone please answer some (or all) of these questions.

1. I have a resource file with the MTM_INFO_FILE resource id. In this resource I have defined mtm_type_uid = 0x10001028;
technology_type_uid = 0x10001671;
Does the mtm_type_uid need to match one of the 4 MTM UID contants as shown below?
Or does it have to be a unique UID to represent my MTM?
0x10001028 SMTP type
0x10001029 POP3 type.
0x1000102B Fax type
0x1000102C SMS type

2. I have created the four dlls that contain classes derived from the 4 MTM base classes. Client, Server, MTM Ui and Ui Data. From a test application, I am creating an instance of my client MTM with this code:

iClientMtm = static_cast<CSenderMtmClient*>( iClientMtmRegistry->NewMtmL( KUidSenderMtm ) ); // KUidSenderMtm is a unique UID 0x10000019

I get a Leave. If I use one of the 4 defined MTM UIDs like 0x10001028, the same code does not leave but the actual Client MTM CSenderMtmClient NewL is never called. I think I am only building the base class. Even the exported E32Dll of my client MTM is never called. I am expecting this to be called when it is loaded because the client's lib file is listed in the test program's mmp file.

// Is this called?   
EXPORT_C TInt E32Dll( TDllReason ) // main function called by E32
    {   
   return KErrNone; // and return
    }

Thanks for any help you can give.
