Use the following command:
telnet servername 110 (standard "pop" POP3 port)

Things to Note:
If local echo is off, turn it on.
The server will return the message "+OK" when you enter a command successfully. Otherwise it will return with something similar to "-ERR 999 Reason of Error".
If you mess up during a command line, backspace may look like you fix the type but when you enter, you will submit garbage to the server. You will have to start the command line again after the server returns an error.

USER useridname
PASS userpassword
STAT (this returns number of messages and the bytes used by the messages.)
LIST (lists a line for each message with the size in bytes of specific messages.)
RTR msg# (from list. Retrieves a message to you. (this downloads it from the server))
TOP msg# (from list. Returns the header and first part of message for review.)
DELE msg# (from list. Marks specified message for deletion. Message is deleted when the user QUITs the session.)
RSET (unmarks previously marked for deletion documents so that the exit/QUIT will not delete them.)
QUIT (close the telnet session and say good-bye to the server)
