I am playing around with mailbox.BabylMailbox to parse
my RMAIL
file. It seems like certain headers are only recognized
some of the
time.  For instance, "Message-Id:" headers sometime
appears, sometimes not. 

The following program:

------------------------------------------------------------------
#!/usr/bin/env python
import mailbox
mb = mailbox.BabylMailbox(
open("/home/students/kurlberg/ggg", "r"))
t = mb.next()
print t.headers
print "\nThe message-id is:", t.getheader("Message-ID")
------------------------------------------------------------------

produces:

------------------------------------------------------------------

<clancey@muga.com>\012', 'Subject: Travel Funds\012',
'Content-Type: text/plain; charset="us-ascii"\012',
'Content-Length: 183\012']

The message-id is: None
------------------------------------------------------------------

The file ggg contains: (I replaced the real domain by
muga.com to
avoid spambots.)

Is there a bug in mailbox/mailbox.BabylMailbox? 

P.S. The above program was run with python version
1.6b1. However,
there are similar problems with python 2.0.

Sorry about the ugly line breaks.
