Create a Sssion with the SendAs Server

Steps

Create a session with the SendAs Server using the RSendAs::Connect() function.
Connect to the server using the default number of message slots available to a session, which is 4, (KSendAsDefaultMessageSlots).
Set the message entry using the CMsvEntry::SetEntryL() function.
Get the IDs of all the context children, using the CMsvEntry::ChildrenL() function.
Empty the draft folder before creating a new message using the CleanMessageFolderL() function.

Example

    void DisplayAccountL();
    void CapabilityFilterL();
    void SendL(RSendAsMessage& aMessage);
