/**

 * api2test: public Address[] getFrom()  <p>
 *
 * how2test: Call this API for given message and then check that it returned  <p>
 *	     array of addresses. Write that list out. If this operation is successfull,
 *	     then this testcase passes, otherwise it fails. <p>
 *
 *	     Returns the value of the RFC822 "From" header fields. If this <p>
 *	     header field is absent, the "Sender" header field is used. If <p>
 *	     the "Sender" is also absent, null is returned.
