How to reclaim your emails and attachment from gmail.

gmailreclaim.py

import email, getpass, imaplib, os

detach_dir = '.' # directory where to save attachments (default: current)
#put your username here
user = ""
#put your password here
pwd = ""

# connecting to the gmail imap server
m = imaplib.IMAP4_SSL("imap.gmail.com")
m.login(user,pwd)
m.select("[Gmail]/All Mail") # here you a can choose a mail box like INBOX instead
# use m.list() to get all the mailboxes

resp, items = m.search(None, "ALL") # you could filter using the IMAP rules here (check http://www.example-code.com/csharp/imap-search-critera.asp)
items = items[0].split() # getting the mails id
i = 0
for emailid in items:
    i += 1
    if i > 5012 :
        resp, data = m.fetch(emailid, "(RFC822)") # fetching the mail, "`(RFC822)`" means "get the whole stuff", but you can ask for headers only, etc
        email_body = data[0][1] # getting the mail content
        mail = email.message_from_string(email_body) # parsing the mail content to get a mail object
        try :
            print "["+mail["From"]+"] :" + mail["Subject"]
        except :
            try :
                print "["+mail["From"]+"] :"
            except :

        fp = open("%d.txt"%(i), 'wb')
        fp.write(mail.__str__())
        fp.close()
        #Check if any attachments at all
        if mail.get_content_maintype() != 'multipart':
            continue

        
        # we use walk to create a generator so we can iterate on the parts and forget about the recursive headach
        j = 0
        for part in mail.walk():
            # multipart are just containers, so we skip them
            if part.get_content_maintype() == 'multipart':
                continue

            # is this part an attachment ?

                continue

            filename = part.get_filename()
            counter = 1

            if not filename:
                filename = 'part-%03d%s' % (counter, 'bin')
                counter += 1

            att_path = os.path.join(detach_dir, filename)

            #Check if its already there
            att_path = att_path.replace("?","")
            att_path = att_path.replace("=","")
            att_path = att_path.replace(" ","")

Je suis pas sur de ce que tu veux faire, mais je crois que tu veux utiliser OfflineIMAP.
