The fetch method gives this error:
imaplib.IMAP4.error: FETCH command error: BAD [b'Could not parse command']
I am not attaching all of my code. I want to get the unseen msg using imap to get the body and save it as text and then download the attachment.
import imaplib, email, os
user= "test9101997"
password="Monday#123"
imap_url="imap.gmail.com"
attach_dir='E:\PROJECT\attachment'
filePath='D:\ATTACH'
con=imaplib.IMAP4_SSL(imap_url)
con.login(user,password)
con.select('INBOX')
#UIDs=con.search(None,'UNSEEN')
#print(UIDs)
(result, messages) = con.search(None, 'UnSeen')
if result == "OK":
for message in messages:
try:
ret, data =con.fetch(message,'(RFC822)')
except:
print ("No new emails to read.")
#self.close_connection()
#exit()
#result, data=con.fetch(i,'(RFC822)')
raw=email.message_from_bytes(data[0][1])
I think you may be confused about the return value of con.search(). If you take a look at the value of messages after that call (assuming that result is OK), it's collection of strings, not a list of message ids. That is, after a call like:
result, messages = con.search(None, 'UnSeen')
The value of messages may look something like:
['1 2 15 20']
So when you try to iterate over it like this:
for message in messages:
The value of message in the first loop iteration will be 1 2 15 20, and that's why you're getting the command error: the request you're making doesn't make any sense. You'll want to do something like this instead:
(result, blocks) = con.search(None, 'UnSeen')
if result == "OK":
for messages in blocks:
for message in messages.split():
ret, data = con.fetch(message, '(RFC822)')
raw = email.message_from_bytes(data[0][1])
There's really no good reason for the imaplib module to return data in this fashion.

To avoid errors when I have to send a group of messages that is larger than max size, I wrote a class useful to send bunch of messages.
Well, first of all would be wonderful if somebody could show me an example that explains how to avoid this problem.
Trying to solve the problem by myself I found extremely hard understanding the size of the message (ServiceBusMessage).
The method sb_msg.message.get_message_encoded_size() it’s the nearest thing of what I need.
Do you know how to calculate the message size?
def send_as_json(self, msg, id_field=None, size_in_bytes=262144):
if isinstance(msg, list):
payload = self.topic_sender.create_message_batch(size_in_bytes)
for m in msg:
try:
# add a message to the batch
sb_msg = ServiceBusMessage(json.dumps(m), message_id=m.get(id_field, uuid.uuid4()), content_type='application/json')
total_size = payload.size_in_bytes + sb_msg.message.get_message_encoded_size()
if total_size > size_in_bytes:
_log.info(f'sending partial batch of {payload.size_in_bytes} bytes')
self.send_service_bus_message(payload)
payload = self.topic_sender.create_message_batch(size_in_bytes)
payload.add_message(sb_msg)
except ValueError as e:
# ServiceBusMessageBatch object reaches max_size.
# New ServiceBusMessageBatch object can be created here to send more data.
raise Exception('', e)
self.send_service_bus_message(payload)
else:
sb_msg = ServiceBusMessage(json.dumps(msg), message_id=msg.get(id_field, uuid.uuid4()), content_type = 'application/json')
self.send_service_bus_message(sb_msg)
Azure ServiceBus - Python:
Below code will give you a insight on how to send batch of messages:
def send_batch_message(sender):
# create a batch of messages
batch_message = sender.create_message_batch()
for _ in range(10):
try:
# add a message to the batch
batch_message.add_message(ServiceBusMessage("Message inside a ServiceBusMessageBatch"))
except ValueError:
# ServiceBusMessageBatch object reaches max_size.
# New ServiceBusMessageBatch object can be created here to send more data.
break
# send the batch of messages to the queue
sender.send_messages(batch_message)
print("Sent a batch of 10 messages")
For more detail information you can visit below Microsoft docs, In this link we have clear information of sending messages as single, list or batch: Link
How to find the size of message:
With the help of below function we can find the size of the message in bytes:
Import sys
sys.getsizeof(variable_name) #this gives us the bytes occupied by the variable.
To check the max_size_in_bytes of a batch, we can simply print below message
batch_message = sender.create_message_batch() # Step1
batch_message.add_message(ServiceBusMessage("Message we want to add")) #Step2 Add message to the batch in a loop.
print(batch_message) #Step3 We will get the output as below as yellow after printing, below is the output:
Output:
ServiceBusMessageBatch(max_size_in_bytes=1048576, message_count=10)
I have a problem sending proactive messages using the Bot Framework with Python.
First what I need is to get the message body from Outlook, and then the bot must send that as a message to all the chats where it was added.
To do that, first I created a new file and called it Email.py.
To read every incoming message body I simply used while true: and time.sleep()
Here is my code example:
import imaplib, email, getpass
from email import policy
import json
import time
imap_host = 'outlook.office365.com'
imap_user = 'xx#xx.com'
# init imap connection
mail = imaplib.IMAP4_SSL(imap_host, 993)
rc, resp = mail.login(imap_user, 'xxxxxx')
while True:
# select only unread messages from inbox
mail.select('Inbox')
status, data = mail.search(None, '(UNSEEN)')
if not data[0].split():
time.sleep(120)
# Bot message variable
Message_for_bot = ''
# for each e-mail messages
for num in data[0].split():
# get a single message and parse it by policy.SMTP (RFC compliant)
status, data = mail.fetch(num, '(RFC822)')
email_msg = data[0][1]
email_msg = email.message_from_bytes(email_msg, policy=policy.SMTP)
# print only message parts that contain text data
for part in email_msg.walk():
if part.get_content_type() == "text/plain":
for line in part.get_content().splitlines():
Message_for_bot += '\n' + line
print(Message_for_bot)
After I successfully created a program to read and print all incoming messages, I tried to build my bot. I found a proactive message bot on the Internet and used it as an example.
First I thought to just run this file with os in the background, but then my bot wasn't running. So then I tried adding an async function in the bot file but it didn't work. My bot just ignores that function. (Then I found the async functions in activity_handler.py, but I didn't find any that could help me.)
Then I tried adding an on_message_activity function and thought maybe it will start working if I call the bot like "#bot hi" for example in Teams. For that idea I must always run the while cycle and never stop the bot, but then I just get a message, and if there's a new incoming message then the bot doesn't write it anymore, and it's not a solution because if the bot is used for multiple chats then it simply doesn't work this way.
Then I try include my code on on_members_added_activity it seems working on azure test in web chat perfectly, but in teams after 1-2 messages stopping to work.
my code
async def on_members_added_activity(
self, members_added: [ChannelAccount], turn_context: TurnContext
):
imap_host = 'outlook.office365.com'
imap_user = 'xxxxxx#xxxxxx.com'
# init imap connection
mail = imaplib.IMAP4_SSL(imap_host, 993)
rc, resp = mail.login(imap_user, 'xxxxxx')
while True:
# select only unread messages from inbox
mail.select('Inbox')
status, data = mail.search(None, '(UNSEEN)')
if not data[0].split():
time.sleep(5)
# Bot message variable
Message_for_bot = ''
# for each e-mail messages
for num in data[0].split():
# get a single message and parse it by policy.SMTP (RFC compliant)
status, data = mail.fetch(num, '(RFC822)')
email_msg = data[0][1]
email_msg = email.message_from_bytes(email_msg, policy=policy.SMTP)
# print only message parts that contain text data
for part in email_msg.walk():
if part.get_content_type() == "text/plain":
for line in part.get_content().splitlines():
Message_for_bot += '\n' + line
await turn_context.send_activity(f"{Message_for_bot}")
for member in members_added:
if member.id != turn_context.activity.recipient.id:
await turn_context.send_activity(
"bot starting work..."
)
So maybe it's possible to send a message to wherever the bot is added (it needs to get this information somehow, maybe it's kept in the bot memory) whenever Message_for_bot is not empty.
All help will be appreciated.
As we have discussed some logic has to change
Move your code out of the on_members_added_activity function
Use Proactive concept to send the message

I'm trying to receive emails on python with poplib, when I run the code I keep getting the following output sequence item 0: expected str instance, bytes found. Here is the whole code, if anyone knows a much simpler way of printing the receiving mail, I would appreciate if you could comment it. I would also like to be able to print only the emails of an determinate email. Thankyou.
import poplib
from email import parser
pop_conn = poplib.POP3_SSL('pop.gmail.com')
pop_conn.user('mail#gmail.com')
pop_conn.pass_('password')
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]
print(message.keys())
for message in messages:
print(message['subject'])
print(message.get_payload())
pop_conn.quit()
The problem arises in your line
messages = ["\n".join(mssg[1]) for mssg in messages]
Here you are trying to join "\n" which is a string, with mssg[1] which is technically a list, and it contains bytes strings. To make that specific line work, you can do messages = [b"\n".join(mssg[1]) for mssg in messages] (notice the b) to make it work. However you will again run into problems when calling parsestr() of Parser, because what you are parsing to it is again mssg[1], which is not a string. Look into the documentation of email.Parser it should have a function which accepts bytes instead of strings as input.
Also I personally would use IMAP instead of POP.
I'm using SendGrid to send emails from my python-based Heroku app.I'm okay with it taking 10 or so minutes to get to my inbox, but I'm receiving three copies of the message and I can't figure out why. Here is the relevant code:
import sendgrid
from sendgrid import SendGridError, SendGridClientError, SendGridServerError
sg = sendgrid.SendGridClient('xxx#heroku.com', 'xxx')
message = sendgrid.Mail()
message.add_to('John Doe <xxx#xxx.com>')
message.set_subject('Example')
message.set_html('Body')
message.set_text('Body')
message.set_from('Dark Knight <xxx#xxx.com>')
message.add_attachment('image.jpg', './image.jpg')
status, msg = sg.send(message)
#app.route('/test2')
def test2():
sg.send(message)
return "sent"
When I go to the relevant route I get 'sent' returned and the email is sent, but again, it send three copies. I'm not sure why. Any help would be great.
Emails one and two:
status, msg = sg.send(message) would send two emails and then set status and msg to the response object.
Email three: after you load the route sg.send(message) sends the next email.
I suggest you to use sendgrid sendmail api to send email. its efficient, fast way to send emails.
You are calling sg.send(message) three times in your code.
It is called twice here: status, msg = sg.send(message) - this will send one mail for status and log it's response to that variable. It will then send again for msg and log it's response to that variable as well.
Then when the user hits the /test2 the function is called again, making it three messages in total.
Here's how you might change it to log responses but just send the one message out:
import sendgrid
from sendgrid import SendGridError, SendGridClientError, SendGridServerError
sg = sendgrid.SendGridClient('xxx#heroku.com', 'xxx')
def sendMessage(options):
message = sendgrid.Mail()
message.add_to('John Doe <xxx#xxx.com>')
message.set_subject('Example')
message.set_html('Body')
message.set_text('Body')
message.set_from('Dark Knight <xxx#xxx.com>')
message.add_attachment('image.jpg', './image.jpg')
// send the message and log the results to status
msg = sg.send(message)
return msg
#app.route('/test2')
def test2():
// send the message, pass any options like email address (not required)
status = sendMessage(options)
return status
I've added a new function above to send out the message and given it an optional options var, so you could use that to pass things to the message, like a different email address, or subject.
I can't figure out the problem and want some input as to whether my Python code is incorrect, or if this is an issue or design limitation of Python XMPP library. I'm new to Python by the way.
Here's snippets of code in question below. What I'd like to do is read in a text file of IM recipients, one recipient per line, in XMPP/Jabber ID format. This is read into a Python list variable.
I then instantiate an XMPP client session and loop through the list of recipients and send a message to each recipient. Then sleep some time and repeat test. This is for load testing the IM client of recipients as well as IM server. There is code to alternately handle case of taking only one recipient from command line input instead of from file.
What ends up happening is that Python does iterate/loop through the list but only last recipient in list receives message. Switch order of recipients to verify. Kind of looks like Python XMPP library is not sending it out right, or I'm missing a step with the library calls, because the debug print statements during runtime indicate the looping works correctly.
recipient = ""
delay = 60
useFile = False
recList = []
...
elif (sys.argv[i] == '-t'):
recipient = sys.argv[i+1]
useFile = False
elif (sys.argv[i] == '-tf'):
fil = open(sys.argv[i+1], 'r')
recList = fil.readlines()
fil.close()
useFile = True
...
# disable debug msgs
cnx = xmpp.Client(svr,debug=[])
cnx.connect(server=(svr,5223))
cnx.auth(user,pwd,'imbot')
cnx.sendInitPresence()
while (True):
if useFile:
for listUser in recList:
cnx.send(xmpp.Message(listUser,msg+str(msgCounter)))
print "sending to "+listUser+" msg = "+msg+str(msgCounter)
else:
cnx.send(xmpp.Message(recipient,msg+str(msgCounter)))
msgCounter += 1
time.sleep(delay)
Never mind, found the problem. One has to watch out for the newline characters at the end of a line for the elements in a list returned by file.readlines(), so I had to strip it out with .rstrip('\n') on the element when sending out message.
