/**
* 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.
