cdmail uses POP3 to check if there are any messages for you on
a specified pop mail server. If there are, it shows the From:
and Subject: lines of the messages in groups of 5 messages starting
with the most recent message. As each group of messages are shown 
you can delete specific messages. You can also undelete all
deleted messages.
