Unable to download TLS Report attachment

[Pedroski55]

I modified your code a little, you seem to have repeated variable names which may have caused confusion.

I wrote Report in the email Subject field.

This still doesn't mark mails as SEEN, also it overwrites a file with the same name without hesitation.

Works for me!

import imaplib
import email
import os
 
# IMAP server credentials
savepath = '/home/pedro/myPython/email_stuff/'
imap_server = "imap.yourmail.com"
sender_of_interest = '[email protected]'
email_address = '[email protected]'
password = 'topsecret'
label = 'INBOX'
subject = 'Report'

# make a folder to hold the files
if 'email_attachments' not in os.listdir(savepath):
    os.mkdir(savepath + 'email_attachments')
 
def connect_to_imap_server(s, e, p):
    # Connect to the IMAP server
    mail = imaplib.IMAP4_SSL(s)
    mail.login(e, p)
    return mail
 
def download_tls_rpt_reports():
    M = connect_to_imap_server(imap_server, email_address, password )
    M.select(label) 
    # Search for emails containing TLS-RPT reports
    #typ, data = imapSession.search(None, 'UNSEEN', f'FROM {sender_of_interest}')
    result, data = M.search(None, 'UNSEEN', f'SUBJECT {subject}')
    for num in data[0].split():
        status, messageParts = M.fetch(num, '(RFC822)')
        emailBody = messageParts[0][1]
        raw_email_string = emailBody.decode('utf-8')
        msg = email.message_from_string(raw_email_string) 
        # Extract JSON attachment (if any)
        for part in msg.walk():
            if part.get_content_type() == "application/json":
                filename = part.get_filename()
                if filename:
                    filePath = os.path.join(savepath, 'email_attachments', filename)
                    with open(filePath, 'wb') as f:
                        f.write(part.get_payload(decode=True))
                        print(f"Saved TLS-RPT report: {filePath}") 
    M.close()
    M.logout()
