Class SimpleSMTPHeader

java.lang.Object
org.apache.commons.net.smtp.SimpleSMTPHeader
public class SimpleSMTPHeader extends Object
This class is used to construct a bare minimum acceptable header for an email message. To construct more complicated headers you should refer to RFC 5322. When the Java Mail API is finalized, you will be able to use it to compose fully compliant Internet text messages.

The main purpose of the class is to facilitate the mail sending process, by relieving the programmer from having to explicitly format a simple message header. For example: 

 writer = client.sendMessageData();
 if (writer == null) // failure
   return false;
 header =
    new SimpleSMTPHeader("foobar@foo.com", "foo@bar.com" "Just testing");
 header.addCC("bar@foo.com");
 header.addHeaderField("Organization", "Foobar, Inc.");
 writer.write(header.toString());
 writer.write("This is just a test");
 writer.close();
 if (!client.completePendingCommand()) // failure
   return false;
