I have the below code, which downloads a Gmail email and its attachments. It returns its attachments.
def gmailAPIDownloadAttachments(self, messageID, userID="me"):
try:
service = self.gmailAPIService
self.GLogger.info("Attempting to download attachments from messageID (" +str(messageID)+ ")")
message = self.gmailAPIGetFullMessage(messageID, userID=userID)
if message is False:
self.GLogger.error("Failed to extract message (" +str(messageID)+ ") for downloading attachments")
return False
attachmentList = list()
payload = message['payload']
if 'parts' in payload:
parts = payload['parts']
for part in parts:
if part['filename']:
if 'data' in part['body']:
data = part['body']['data']
else:
att_id = part['body']['attachmentId']
att = service.users().messages().attachments().get(userId=userID, messageId=messageID, id=att_id).execute()
data = att['data']
file_data = base64.urlsafe_b64decode(data.encode('UTF-8'))
filename = part['filename']
extSearch = filename.find('.')
if extSearch == -1:
ext = ""
partFileName = filename[0:extSearch]
else:
ext = filename[extSearch+1:]
partFileName = filename[0:extSearch]
theAttachment = Attachment(filename,partFileName, ext, file_data)
attachmentList.append(theAttachment)
self.GLogger.info("Successfully downloaded attachments from messageID (" +str(messageID)+ ")")
return(attachmentList)
except:
self.GLogger.error("Encountered an error while attempting to download email attacments from messageID (" +str(messageID)+ ")")
tb = traceback.format_exc()
self.GLogger.exception(tb)
return False
I understand how to convert fetching messages into batching. For example, this is how one could batch-fetch messages:
from apiclient.http import BatchHttpRequest
import json
batch = BatchHttpRequest()
#assume we got messages from Gmail query API
for message in messages:
batch.add(service.users().messages().get(userId='me', id=message['id'],
format='raw'))
batch.execute()
for request_id in batch._order:
resp, content = batch._responses[request_id]
message = json.loads(content)
#handle your message here, like a regular email object
However, the attachments aspect seem to have logic and other possible fetches such as in this part:
att_id = part['body']['attachmentId']
att = service.users().messages().attachments().get(userId=userID, messageId=messageID, id=att_id).execute()
data = att['data']
How can I effectively batch both fetching the message and its attachments? I would like to be able to quickly fetch many emails at once.
I have a Python script to move messages with a certain subject. The messages get marked as read and I don't want them to be marked as read. What part of the script marks them as read and how do I make it not mark as read?
Also, I'm not too sure what I am doing yet, so if there is any redundant code or errors please let me know.
import getpass
from Crypto.Hash import MD5
import sys
import imaplib
import email
import re
password = getpass.getpass()
match = "redacted"
username = "redacted"
dest = "000"
pattern_uid = re.compile('\d+ \(UID (?P<uid>\d+)\)')
def md5(message):
hash = MD5.new()
hash.update(message)
return hash.hexdigest()
md5 = md5(password)
if md5 == match:
pass
else:
print "Mismatch"
sys.exit()
M = imaplib.IMAP4_SSL("mail.redacted.com", 993)
M.login(username, password)
M.select()
typ, data = M.search(None, 'ALL')
M.select('Inbox')
msgs = M.search(None, 'ALL')[1]
num_messages = len(msgs[0].split())
num_messages += 1
def parse_uid(data):
match = pattern_uid.match(data)
return match.group('uid')
for i in range(1, num_messages):
try:
typ, msg_data = M.fetch(str(i), '(RFC822)')
except:
pass
for response_part in msg_data:
if isinstance(response_part, tuple):
UID = M.fetch(str(i),'UID')
UID = UID[1]
try:
UID = parse_uid(UID[0])
except:
pass
msg = email.message_from_string(response_part[1])
for header in [ 'subject' ]:
if msg[header] == "Redacted":
result = M.uid('COPY', UID, dest)
if result[0] == 'OK':
mov, data = M.uid('STORE', UID, '+FLAGS', '(\Deleted)')
M.expunge()
M.close()
M.logout()
typ, msg_data = M.fetch(str(i), '(RFC822)')
Fetching a message body marks it as read. You'll want to use BODY.PEEK[].
Although, I don't know why you're fetching the whole message just to copy it. Why don't you just fetch the headers? Use BODY.PEEK[HEADERS].
I'm trying to get a python script which looks through my gmail inbox using imap and prints out the subject and sender of any emails which are unseen. I've started but at the moment I don't think it can sort the unseen emails or extract from these the subject and sender.
Does anyone know how to finish this code?
import imaplib
import email
user = "x"
password = "y"
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login(user, password)
mail.list()
mail.select('inbox')
unseen_emails = mail.search(None, 'UnSeen')
print unseen_emails
If you were willing to use poplib, this should work.
import poplib
mymail = []
host = "pop.gmail.com"
mail = poplib.POP3_SSL(host)
print (mail.getwelcome())
print (mail.user("user#gmail.com"))
print (mail.pass_("password"))
print (mail.stat())
print (mail.list())
print ("")
if mail.stat()[1] > 0:
print ("You have new mail.")
else:
print ("No new mail.")
print ("")
numMessages = len(mail.list()[1])
numb=0
for i in range(numMessages):
for j in mail.retr(i+1)[1]:
numb+=1
if numb == 4 or numb == 5:
print(j)
mail.quit()
input("Press any key to continue.")
Just be sure to allow less secure apps in your google account here: https://myaccount.google.com/lesssecureapps
My external lib https://github.com/ikvk/imap_tools
from imap_tools import MailBox, AND
# get list of unseen emails from INBOX folder
with MailBox('imap.mail.com').login('test#mail.com', 'pwd', 'INBOX') as mailbox:
for msg in mailbox.fetch(AND(seen=False)):
msg.subject # str: 'some subject 你 привет'
msg.from_ # str: 'Sender#ya.ru'
NOTE: mailbox.fetch has mark_seen arg!
I have a Python script adapted from Downloading MMS emails sent to Gmail using Python
import email, getpass, imaplib, os
detach_dir = '.' # directory where to save attachments (default: current)
user = raw_input("Enter your GMail username:")
pwd = getpass.getpass("Enter your password: ")
# 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, 'FROM', '"Impact Stats Script"') # 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
for emailid in items:
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
#Check if any attachments at all
if mail.get_content_maintype() != 'multipart':
continue
print "["+mail["From"]+"] :" + mail["Subject"]
# we use walk to create a generator so we can iterate on the parts and forget about the recursive headach
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 ?
if part.get('Content-Disposition') is None:
continue
filename = part.get_filename()
counter = 1
# if there is no filename, we create one with a counter to avoid duplicates
if not filename:
filename = 'part-%03d%s' % (counter, 'bin')
counter += 1
att_path = os.path.join(detach_dir, filename)
#Check if its already there
if not os.path.isfile(att_path) :
# finally write the stuff
fp = open(att_path, 'wb')
fp.write(part.get_payload(decode=True))
fp.close()
I am filtering messages by subject and getting the attachments, but now I need to only get attachments from new emails. Can I modify the m.search() somehow to return only unread emails?
Try modifying this line:
resp, items = m.search(None, 'FROM', '"Impact Stats Script"')
to:
resp, items = m.search(None, 'UNSEEN', 'FROM', '"Impact Stats Script"')
The Python imaplib documentation shows just adding more search criteria, and the IMAP specification defines the UNSEEN search criteria:
UNSEEN
Messages that do not have the \Seen flag set.
I am interested to trigger a certain action upon receiving an email from specific
address with specific subject. In order to be able to do so I need to implement
monitoring of my mailbox, checking every incoming mail (in particular, i use gmail).
what is the easiest way to do that?
Gmail provides the ability to connect over POP, which you can turn on in the gmail settings panel. Python can make connections over POP pretty easily:
import poplib
from email import parser
pop_conn = poplib.POP3_SSL('pop.gmail.com')
pop_conn.user('username')
pop_conn.pass_('password')
#Get messages from server:
messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()[1]) + 1)]
# Concat message pieces:
messages = ["\n".join(mssg[1]) for mssg in messages]
#Parse message intom an email object:
messages = [parser.Parser().parsestr(mssg) for mssg in messages]
for message in messages:
print message['subject']
pop_conn.quit()
You would just need to run this script as a cron job. Not sure what platform you're on so YMMV as to how that's done.
Gmail provides an atom feed for new email messages. You should be able to monitor this by authenticating with py cURL (or some other net library) and pulling down the feed. Making a GET request for each new message should mark it as read, so you won't have to keep track of which emails you've read.
While not Python-specific, I've always loved procmail wherever I could install it...!
Just use as some of your action lines for conditions of your choice | pathtoyourscript (vertical bar AKA pipe followed by the script you want to execute in those cases) and your mail gets piped, under the conditions of your choice, to the script of your choice, for it to do whatever it wants -- hard to think of a more general approach to "trigger actions of your choice upon receipt of mails that meet your specific conditions!! Of course there are no limits to how many conditions you can check, how many action lines a single condition can trigger (just enclose all the action lines you want in { } braces), etc, etc.
People seem to be pumped up about Lamson:
https://github.com/zedshaw/lamson
It's an SMTP server written entirely in Python. I'm sure you could leverage that to do everything you need - just forward the gmail messages to that SMTP server and then do what you will.
However, I think it's probably easiest to do the ATOM feed recommendation above.
EDIT: Lamson has been abandoned
I found a pretty good snippet when I wanted to do this same thing (and the example uses gmail). Also check out the google search results on this.
I recently solved this problem by using procmail and python
Read the documentation for procmail. You can tell it to send all incoming email to a python script like this in a special procmail config file

Python has an "email" package available that can do anything you could possibly want to do with email. Read up on the following ones....
from email.generator import Generator
from email import Message
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.mime.multipart import MIMEMultipart

Says you have to have a corporate Gmail, but I have come to find that you can read Gmail free versions without issues. I use this code to get my blood pressure results I email or text to a gmail address.
