Export Gmail using Python imaplib - text mangled with newline issues

Question

I'm using the following code to export all the emails in a specific gmail folder.

Its working well, in that its pulling out all the emails I expect, but it (or me) seems to be mangle the encoding for CR / newlines.

Code:

import imaplib
import email
import codecs
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('myUser@gmail.com', 'myPassword')  #user / password
mail.list()
mail.select("myFolder") # connect to folder with matching label

result, data = mail.uid('search', None, "ALL") # search and return uids instead
i = len(data[0].split())

for x in range(i):
    latest_email_uid = data[0].split()[x]
    result, email_data = mail.uid('fetch', latest_email_uid, '(RFC822)')
    raw_email = email_data[0][1]
    email_message = email.message_from_string(raw_email)
    save_string = str("C:\\\googlemail\\boxdump\\email_" + str(x) + ".eml") #set to   save location
    myfile = open(save_string, 'a')
    myfile.write(email_message)
    myfile.close()

My problem is that by the time I get to the object its littered with '=0A', which I am assuming are incorrectly interpreted newline or carriage return flag.

I can find it in hex, [d3 03 03 0a] but because this is not 'characters' I can't find a way for str.replace() to take the parts out. I don't actually want the newline flags.

I could convert the whole string to hex, and do a do a replace of sorts / regex thing, but that seems like over kill - when the problem is in the encoding / reading of the source data

What I see:

Answer 1

What you are looking at is Quoted Printable encoding.

Try changing:

email_message = email.message_from_string(raw_email)

to:

email_message = str(email.message_from_string(raw_email)).decode("quoted-printable")

For more info see Standard Encodings in the Python codecs module.

Answer 2

Just 2 additional items having gone thought the pain of this for a day. 1 do it at the payload level so you can process your email_message to get email addresses etc from your mail.

2 You need to decode the charset set also, I had trouble with people copying and pasting html from webpages and content from word docs etc into emails that I was then trying to process.

if maintype == 'multipart':
                    for part in email_message.get_payload():
                            if part.get_content_type() == 'text/plain':
                                text += part.get_payload().decode("quoted-printable").decode(part.get_content_charset())

Hope this helps someone !
