POUndoing "marked as read" status of emails fetched with imaplib
text
Body
copied!<p>I wrote a python script to fetch all of my gmail. I have hundreds of thousands of old emails, of which about 10,000 were unread.</p> <p>After successfully fetching all of my email, I find that gmail has marked all the fetched emails as "read". This is disastrous for me since I need to check all unread emails only. </p> <p>How can I recover the information about which emails were unread? I dumped each mail object into files, the core of my code is shown below:</p> <pre><code>m = imaplib.IMAP4_SSL("imap.gmail.com") m.login(user,pwd) m.select("[Gmail]/All Mail") resp, items = m.uid('search', None, 'ALL') uids = items[0].split() for uid in uids: resp, data = m.uid('fetch', uid, "(RFC822)") email_body = data[0][1] mail = email.message_from_string(email_body) dumbobj(uid, mail) </code></pre> <p>I am hoping there is either an option to undo this in gmail, or a member inside the stored mail objects reflecting the seen-state information. </p> <p>For anyone looking to prevent this headache, consider this answer <a href="https://stackoverflow.com/questions/10991533/imaplib-gmail-how-to-download-full-message-all-parts-while-not-marking-read">here</a>. This does not work for me, however, since the damage has already been done.</p> <p>Edit: I have written the following function to recursively "grep" all strings in an object, and applied it to a dumped email object using the following keywords:</p> <pre><code>regex = "(?i)((marked)|(seen)|(unread)|(read)|(flag)|(delivered)|(status)|(sate))" </code></pre> <p>So far, no results (only an unrelated "Delivered-To"). Which other keywords could I try?</p> <pre><code>def grep_object (obj, regex , cycle = set(), matched = set()): import re if id(obj) in cycle: return cycle.update([id(obj)]) if isinstance(obj, basestring): if re.search(regex, obj): matched.update([obj]) def grep_dict (adict ): try: [ [ grep_object(a, regex, cycle, matched ) for a in ab ] for ab in adict.iteritems() ] except:pass grep_dict(obj) try:grep_dict(obj.__dict__) except:pass try: [ grep_object(elm, regex, cycle, matched ) for elm in obj ] except: pass return matched grep_object(mail_object, regex) </code></pre>
