Notes/Domino 4 and 5 Forum

Hi,
I have two questions:

1. I am trying to the Mail Gateway to access the mail by calling MailOpenMessageFile(...) and MailCreateMessageList(...), it returns every documents.
How can I just access the Inbox?

2. I have this code
if (Ret = MailOpenMessageFile(szMailFilePath, &hMessageFile))
{
return( Ret );
}

Ret = MailCreateMessageList(hMessageFile, &hMessageList, &MessageList, &NbMessages );

for( i = 0; i < NbMessages; i++ )
{
sprintf( ListMsgId[i].MsgId, "%ld", i );
ListMsgId[i].LgMsgId = strlen( ListMsgId[i].MsgId );
}

Is there a way to have a message number unique?

I would like to call "MailOpenMessage" with a message number unique.

MailOpenMessage (MessageList, uniqueID, &hMessage )

Merci.. for your patience..
