Sends the RETR command.
The RETR command requests that the server send a complete message. The argument of the RETR command is a message sequence number that specifies a message in the POP3 mailbox.
The server's response is a multiple line reply. To get the message, you must have a method that the library calls for each line of the message. You provide this method as a delegate in the lines parameter. Each line of the response contains a line of the message.
