Hi I am trying to send mail with smtp.lib inside my python tkinter project,but I am getting an error and I cant seem to find a solution to this problem when trying to use my email. I have been trying and testing for days now.
Please let me know what I'm doing wrong and why I'm getting this error. The code below is below there.
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1131)
for treeitems in list_of_lists:
FILES = (treeitems[0])
EMAILS = (treeitems[1])
subject = subject_entry.get()
body = Email_box.get("1.0","end")
sender_email = Email_entry.get()
receiver_email = EMAILS
password = EPassword_entry.get()
message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = subject
# message["Bcc"] = receiver_email
#addded this also the encode part
message.attach(MIMEText(body, "plain"))
filename = FILES # In same directory as script
with open(filename, "rb") as attachment:
part = MIMEBase("application", "octet-stream")
part.set_payload(attachment.read())
encoders.encode_base64(part)
part.add_header(
"Content-Disposition",
f"attachment; filename= {filename}",)
message.attach(part)
text = message.as_string()
context = ssl.create_default_context()
with smtplib.SMTP_SSL(Server_entry.get(),Port_entry.get(), context=context) as server:
server.login(sender_email, password)
try:
check_results = server.sendmail(sender_email, receiver_email, text)
except smtplib.SMTPRecipientsRefused:
continue
except smtplib.SMTPAuthenticationError:
continue
except UnicodeEncodeError:
continue
except ssl.SSLCertVerificationError:
continue
check_list.append(check_results)
for x in range(len(list_of_lists)):
ProgBar["value"] = (len(check_list))
root.update_idletasks()
print(len(check_list))
messagebox.showinfo("Report","Emails sent!")
time.sleep(2)
check_error_mails()
time.sleep(1) ```
