Programatically Getting POP3 Message Unique Id and Message Size

I need to access a POP3 email account and obtain the the list of messages' unique id and its co开发者_开发知识库rresponding file size. I'm using CodeIgniter and have access to Zend libraries. Trying to do something similar to the LIST command. Ideas?

Take a look into "Reading Mail Messages" in the Zend Framework documentation. Zend_Mail_Storage_Pop3 is what you are looking for.
