/**
 * PHPMailer POP-Before-SMTP Authentication Class.
 * Specifically for PHPMailer to use for RFC1939 POP-before-SMTP authentication.
 * 1) This class does not support APOP authentication.
 * 2) Opening and closing lots of POP3 connections can be quite slow. If you need
 *   to send a batch of emails then just perform the authentication once at the start,
 *   and then loop through your mail sending script. Providing this process doesn't
 *   take longer than the verification period lasts on your POP3 server, you should be fine.
 * 3) This is really ancient technology; you should only need to use it to talk to very old systems.
 * 4) This POP3 class is deliberately lightweight and incomplete, implementing just
 *   enough to do authentication.
 *   If you want a more complete class there are other POP3 classes for PHP available.
