parse output screen ok but cant get desired output new file!

P: n/a
By the way list is there a better way than using the readlines() to
parse the mail data into a file , because Im using
email.message_from_file it returns
all the data i.e reads one entire line from the file , headers as wellas just the desired body messages .

fp = file("/home/chuck/pythonScript/testbox")
mb = mailbox.UnixMailbox(fp,
email.message_from_file)
mailout = file("/home/chuck/pythonScript/SurveyResults.txt","w")
for mail in fp.readlines():
mailout.write(mail)

Something like this>

for mail in mb:
body = mail.get_payload()
mailout.write(body) # write only the body messages to SurveyResults.txt
Cheers if the is a better way I can't get my head round how I can printmail (
only the body messages) to screen and the entire mail headers and bodyto the new file.

Hi have any one got any suggstions to my script I can parse the emailbody messages to screen but I want the same desired effect to save to anew file.I have tried a few things to no effect. .

There's a lot going on in your message. I *think* what you want
is the suggestion to replace
for mail in fp.readlines():
mailout.write(mail)
with
mailout.write(fp.read())

Hi again where I print mail.get_payload()
I want to write this to the file. Bu uisng readlinds() function I
obviously get the entire contents including the headers thus I want to
do something like this for bdymsg in mb:
bdymsg = mail.get_payload()
print mail.get_payload()# prints body msg's to screen
mailout.write(bdymsg)
# mailout.write(mail.get_payload()) # Something along these lines.
mailout.close()

I wrote something a couple of weeks ago that might help.
It works with POP3 mailboxes and it handles messages with
body text and/or attachments, but you could easily change
it.

Hope it helps.
