Keine Ahnung wenn ich ehrlich bin.
Aber wenn ich mir so das Produkt anschaue und auch den java-code dann sehe ich das hier:

public static final String TO = "TO";
public static final String FROM = "FROM";
public static final String CC = "CC";
public static final String BCC = "BCC";
public static final String REPLYTO = "REPLYTO";
Von daher würde ich es mal ganz profan so versuchen:
