I'm writing a Python script to process emails returned from Procmail. As suggested in this question, I'm using the following Procmail config:
:0:
|$HOME/process_mail.py
My process_mail.py script is receiving an email via stdin like this:
From hostname Tue Jun 15 21:43:30 2010
Received: (qmail 8580 invoked from network); 15 Jun 2010 21:43:22 -0400

I'm trying to parse the message in this way:
>>> import email
>>> msg = email.message_from_string(full_message)
I want to get message fields like 'From', 'To' and 'Subject'. However, the message object does not contain any of these fields.
What am I doing wrong?
The easiest tool I've found for reading emails in Python is imap_tools. It has an elegant interface to communicate with your email provider using IMAP (which almost every email provider will have). First, you access the MailBox; for which you need to get the IMAP server and login credentials (username and password).
You must ensure that the lines are not accidentally broken (as they are above, though it's hard to say if that was a copy-paste problem) -- with an intact message such as:
Received: (qmail 8580 invoked from network); 15 Jun 2010 21:43:22 -0400

then
msg = email.message_from_string(msgtxt)
print msg['Subject']
prints TEST 12
as desired.
