This will print out the first 20 chars of each undeleted message.  You
should be able to figure out how to do what you want from it.

>>> import imaplib
>>> i = imaplib.IMAP4("mail.example.com")
>>> i.login("username", "password")
('OK', ['[CAPABILITY IMAP4REV1 IDLE NAMESPACE MAILBOX-REFERRALS BINARY
UNSELECT SCAN SORT THREAD=REFERENCES THREAD=ORDEREDSUBJECT MULTIAPPEND] User
username authenticated'])
>>> i.select()
('OK', ['12'])
>>> for msg_num in i.search(None, "UNDELETED")[1][0].split():
... 	msg = i.fetch(str(msg_num), "RFC822")
... 	print msg[1][0][1][:20]
...

Simply playing around with an imaplib.IMAP4 class in an interactive prompt,
with imaplib.debug set to 4 and a copy of the RFC handy is the best way to
learn.
