simple script to read and parse mailbox

P: n/a
Hi , Im trying to parse a specific users mailbox (testwwws) and output
the body of the messages to a file ,that file will then be loaded into a
PostGresql DB at some point .

I have read the email posts and been advised to use the email Module
and mailbox Module.

The blurb from a memeber of this list . Im not at work at the moment So
I cant test this out , but if someone could take a look and check that
im on the write track as this Monday I need to show my Boss and get the
body data out of the user's mailbox.

**Blurb form a member who's directed me**

Thus started with the mailbox and email modules. Mailbox lets you iterate over a
mailbox yielding individual messages of type email. The e-mail object lets
you parse and operate on the message components. From there you should be
able to extract your data.


## The email messages is read as flat text form a file or other source,
##the text is parsed to produce the object structure of the email message.
#!/usr/bon/env python
import mboxutils
import mailbox
import email
import sys
import os
import rfc822
import StringIO
import email.Parser
import types

# email package for managing email messages
# Open Users Mailbox
# class Message()
#mbox = mailbox.UnixMailbox(open("/var/spool/mail/chucka"))

def main():

# The Directory that will contain the Survey Results

dir = "/tmp/SurveyResults/"

# The Web Survey User Inbox
# Mailbox /home/testwwws/Mail/inbox

maildir = "/home/testwwws/Mail/inbox"
for file in os.listdir(maildir):

print os.path.join(maildir, file)

fp = open(os.path.join(maildir, file), "rb")
p = email.Parser.Parser()
msg = p.parse(fp)
fp.close()
#print msg.get("From")
#print msg.get("Content-Type")

counter = 1
for part in msg.walk():
if part.get_main_type() == 'multipart':
continue

filename = part.get_param("name")
if filename==None:
filename = "part-%i" % counter
counter += 1
fp = open(os.path.join(dir, filename), 'wb')
print os.path.join(dir, filename)
fp.write(part.get_payload(decode=1))
fp.close()
if __name__ == '__main__':
main()

Cheers all this list has been very helpful.

Hi again Chuck,

I've been reading a few of your posts and I'm wondering. Are the
emails that you're parsing have binary attachments, like pictures and
stuff, or are you just trying to get the text of the body?

Or is it a little of both? It looks like you're expecting emails with
multiple binary attachments.

Other than that it looks good. You can access the header fields
directly, like:

print msg['From']

Save you a little typing.

Just Trying to get the body of the messages .

I have built and developed a dtml zope web form that encapsulate the
survey data.
Thus the created user testwwws mail box with have the results that I
must parse and process to a file that I can then use to populate a
database .

Cheers Chuck

Well I did hack most of the code . I was trying using the mboxutils
module but I could only get the headers . I assume form this script I
can get the text of the body . The reason I haven't tested is while at
work I started the write (Oops Hack ) the script then emailed it home .
Because I use pop3 account I onlt have a /var/spool/mail/Chucka not as
in work /home/User/Mail/inbox that I usuaslly scan to view data in inbox.

So please re-affirm that my hack script will be able to parse the text
of the body ( No attachments of binaries will exist within the email
messages.

Cheers for you help.

print msg['Body']

I just need the text of the body. But from your psi I can -

Ah, the problem is far too simple for our complicated minds.
just do:
body = msg.get_payload()
That will give you the plain text message body of an email

get_payload(decode=True) is for binary stuff (or maybe unicode, maybe)
all that get_content_type(),get_param() stuff can be ignored if you're
just doing plain text
The script you are adapting is for multiple binary (like pictures)
attachments

So, looking at the doc page for mailbox there's an interesting code
fragment:

import email
import mailbox
mbox = mailbox.UnixMailbox(fp, email.message_from_file)

So if you emails are all plain/text you could just write:

import email
import mailbox
fp = open("/var/spool/mail/chucka")
mbox = mailbox.UnixMailbox(fp, email.message_from_file)
bodies = []
for msg in mbox:
body = msg.get_payload()
bodies.append(body)

Which will leave you with a list of strings, each one a message body.

msg = email.message_from_file(fileobj) does the same thing as

p = email.Parser.Parser()
msg = p.parse(fileobj)

it's just a short cut
As is passing Unixmailbox email.message_from_file as a handler

You could also do

fp = open("/var/spool/mail/chucka")
mbox = mailbox.UnixMailbox(fp) # no handler
for mail in mbox:
msg = email.message_from_file(mail) # handle here
body = msg.get_payload()

Hi all exspecailly fishboy here's the script I'm just waiting to get
confirmation where im going to run the script form.

I have added a output =('/tmp/SurveyResults','w+a') which I believe will
process the body messages data to this file for future work ie database
loading.

Also that using I can add 'a' opens the file # for appending any data written
to the file is automatically added to the end.Is this logical .I have tried to
# comments to aid my learning process So bear with me.

Sorry to bovver you again (again) here's script.

I still can't see why the get_payload() doesn't produce
the plain text message body of an emails in the testwwws users mailbox.
AS you can see I have tried a few things but no joy what am I missing.

Cheers

Chuck
