parsing downloaded mail via POP3

[Kevin F]

I have the following script:

emails = []
for msg in messagesInfo:
         msgNum = int(msg.split()[0])
         msgSize = int(msg.split()[1])
         if(msgSize < 20000):
            message = server.retr(msgNum)[1]
            Message = join(message, “\n”)
emails.append(message)


It downloads messages for me via my POP3 server, however, the message 
format (attached below) includes ridiculous amounts of data and I just 
want to return the from, subject, and body.  Any pointers on how to do this?
