Errors receiving emails with imaplib, from a specific inbox

问题

When reading emails from a specific folder (Office365), the body of the message is a random long string that makes no sense.

Initially, I sent those emails to my personal mail as copy, to a specific folder. Reading from there I haven't had problems. But when I try to read directly from the main inbox, the messages are long strings that makes no sense (so, I can´t parse anything)

mail = imaplib.IMAP4_SSL(SMTP_SERVER)
     mail.login(FROM_EMAIL, FROM_PWD)
     boxes = mail.list()
     mail.select('INBOX/netstatus', readonly=True) 
     (type, data) = mail.uid('SEARCH', None, '(UNSEEN)') 
     mail_ids = data[0]
     id_list = mail_ids.split()


def read_email(self, *id_list):
    id_list = list(id_list)
    for i in reversed(id_list):
        (typ, data) = mail.uid('FETCH', i, '(RFC822)')
    for response_part in data:                  
        if isinstance(response_part, tuple):
            print("Response: ",response_part)
            msg = \         email.message_from_string(response_part[1].decode('utf-8'))                                                                       

            body = ''
            email_subject = msg['subject']
            email_from = msg['from']
            email_date = msg['date']
            message= msg.get_payload().encode('utf-8')
            print(message)

I receive something like this when I read from my personal inbox:

mymail: b'Status from Device (x.x.x.x) to AnotherDevice (y.y.y.y), interface A B, in Protocol came up\r\n'

But when I read from the main inbox:

'QWRq4N5IGZyb20gVVREFxLXJlMSAuMTAuMjUsIDAxMDAuMTAwMS4w\r\nMDI1LjAwKSB0byBVU0FEQUxIERS4MC4xMC4xMMDAxLjAw\r\nMjUuMDQpLCBpbnZhY2UgMTAuMTA4AuMjI5IHRvIDEwLjEwLjIwLjEzMCwgaW4gSVNJUy9M\r\nZXZlbDIgd2VudCBkkNvbmZ3VyZWQgd2F0Y2hsaXN0OiI1OQ0K\r\n'

With Python3.6 or later, you can use EmailMessage.get_content() to decode the encoded content automatically.

import email
from email import policy

# Email based on one of the examples at https://docs.python.org/3.6/library/email.examples.html

s = """
Subject: Ayons asperges pour le =?utf-8?q?d=C3=A9jeuner?=

msg = email.message_from_string(s, policy=policy.default)
print(msg.get_content())

For multipart messages you need to iterate over the parts:

for part in msg.iter_parts():
    print(part.get_content())
