simple script to read and output Mailbox body to file.

P: n/a
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.

Is the another snippet in relation to get_payload to access the body contents
print and process to a file.

Cheers

Chuck

You still haven't answered central questions.
- Do you want email bodies in separate files, or all email bodies in
one file?
- Do you want to collect these email bodies as they come in, or
periodically from a 'mbox' file?

Ok, you dont need to pass UnixMailbox email.message_from_file if your
going to explictly parse later with msg = email.message_from_file(fp)

Your parsing the email message twice.

If there are still problems, try breaking it down a bit

mbox = mailbox.UnixMailbox(fp)
for mail in mbox:
print mail.read()
break #just look at one message

'mail' is a file obj pointing at a single email, so print mail.read()
should display one email, with headers. If that doesn't work we have
problems before we get anywhere

If that gives us something sensible for an output, try parsing the
email.

mbox = mailbox.UnixMailbox(fp)
for mail in mbox:
msg = email.message_from_file(mail)
print `msg` #backticks
print msg['Subject']
print msg.get_content_type()
break #just look at one message

Should give us something like:

<email.Message.Message instance at 0xa0e442c>
Re: Best IDE?
text/plain

And if that works, then

msg.get_payload() should return the body.

Hi There ,

I would like all email bodies in one file.Collect these email bodies as they come in, or periodically from a 'mbox' file? using cron.

I would lie cron to run the script and empty the mail user box in question to a file for extraction to a database.

Cheers

I have tried breaking it down a bit as per your post.
when I run it I still dont see any results even to my output file .
Im logged in as myself ansd trying to access the mailbox on the mailserver
which is mounted via nfs.The mail server has only version Python 1.5 So doesnt
know about the email module.

Cheers

output =('/tmp/SurveyResults','w')

fp = open("/var/spool/mail/chuck")
mbox = mailbox.UnixMailbox(fp)
for mail in mbox:
print mail.read()

What does a
$less /var/spool/mail/chuck
give you?

UnixMailbox is expecting a single file with all the emails
concatenated in it. UnixMailbox just splits them out one at a time.

Hrmmm, looking in the source, it recommends that you use
PortableUnixMailbox instead. If you can see the emails with the
'less' command, maybe that will work.

If you don't see any emails with 'less', I'm left wondering where your
emails are at?

Since your running Linux, you can simply do manual or periodic parsing
of mbox file and put the email bodies into 'file',
formail -I '' -s < mbox >> file
Or, use Procmail recipe as email comes in,
:0 b:
* some_condition
| cat >> file

Ref:
man formail procmail procmailrc procmailex

Homework:
Translate it to Python.

Hi again I using this to test as instructed it runs on my local machine with
my /var/spool/mail/chuck dir
thats mounted on the mail server using nfs .
Thus I still get no output only when I print mbox.

NB Im digesting formail doc's and man pages.

Cheers

Nice One I was thinking I was going mad at home this works .
But $ less /var/spool/mail/chuck produced no output.

I use scan+ to check and go thru users email folder . i.e

cd /home/User/Mail/Inbox <Folder in Question> say spam Folder
scan +Lottery > show 1 example below:


chuck@sevenofnine:~/pythonScript> cd /home/chuck/Mail

Hi again yes the /var/spool/mail/chuck is empty as we process the mail to the
user home dir using MH .
Thus created a mailbox using packf with three emails for testing .

Cheers for pointing this out.

This now works ! as you stated below.Now all the body messages is this down
using bodies [] list.

Cheers Chuck

mbox = mailbox.UnixMailbox(fp)
for mail in mbox:
msg = email.message_from_file(mail)
print `mail` #backticks
print mail['Subject']
print mailget_content_type()
break #just look at one message

Gives me this:

chuck@sevenofnine:~/pythonScript> python getSurveyMail.py

that works, then I done this

msg.get_payload() should return the body. How about all the body messages in
file.

Thanks

Hi After createing a mailbox using packf
packf +/home/chuck/testwwws all -file testbox and thus cp 3 5 6 (emails) .

I get output with this except only one email header and body message , the
commented out stuff , does that iterate or can it produce all current 3 email
body messages. Cheers Im nearly there.

for mail in mbox:
# body = mail.get_payload()
# bodies.append(body)
# msg = mail.message_from_file(mail)
print 'mail'
print mail['Subject']
print mail.get_content_type()#text/plain
print mail.get_payload()
break # just look at one message

Hi all forget my last post about all email body messages I added a comment
before break . Sorry for reading my own comments lines.

I get output desired .Now to pass to an external File.

for mail in mbox:
# body = mail.get_payload()
# bodies.append(body)
# msg = mail.message_from_file(mail)
print 'mail'
print mail['Subject']
print mail.get_content_type()#text/plain
print mail.get_payload()
# break # just look at one message

Hi again

I get output desired .Now to parse the fileobject and all body messages to an
external File named SurveyResults.txt
Is this the correct way to go about it .

for mail in mbox:
# body = mail.get_payload()
# bodies.append(body)
# msg = mail.message_from_file(mail)
print 'mail'
print mail['Subject']
print mail.get_content_type()#text/plain
print mail.get_payload()
# break # just look at one message

# The File SurveyResults.txt must all ready exist.
output = open("SurveyResults.txt", 'w') # mode 'w' means open the file for
writ-ing (any data already in the file will be erased)
mailout = mail.get_payload()
output. writelines(mailout)

output. close() # this is at end of the script

Here's my error but I thought mail is my file

Traceback (most recent call last):
File "getSurveyMailRev2.py", line 37, in ?
mailout = mail.get_payload()
NameError: name 'mail' is not defined

Hi please could someone point to what I have done wrong as the script runs
with no errors but the file I am trying to parse the print statement output
too instead of just the screen/command line to another file.

I have digested the Input and Output and text formatting docs and I read
something about using stdout to a file . Can someone point me in the right
direction.
