* The JavaMail API supports a debugging option that will can be very
* useful if you run into problems. You can activate debugging on any of the
* mail classes by calling setDebug(true). The debugging output will be written
* to System.out.
*
* Sometimes you want to experiment with various security setting or features of
* commons-email. A good starting point is the test class EmailLiveTest and
* EmailConfiguration which are used for testing commons-email with real SMTP
* servers.
