'SMTP_SSL' object has no attribute 'sendemail'

The error message "SMTP_SSL object has no attribute 'sendemail'" typically occurs when you're trying to use a function or method called `sendemail` on an instance of the `SMTP_SSL` class in the Python Standard Library's `smtplib` module, but that method doesn't exist.

In Python's `smtplib`, the `SMTP_SSL` class is used for sending email over an SSL-encrypted connection (SMTPS). The correct method to use for sending an email is usually `sendmail()`, not `sendemail`. Here's a basic example of how to send an email using `SMTP_SSL`:

import smtplib
from email.mime.text import MIMEText

# Set up your email details
sender = "your_email@example.com"
receiver = "recipient@example.com"
message = MIMEText("Your message here")

# Connect to the SMTP server using SSL
smtp_server = "smtp.example.com"
port = 465  # For SSL
smtp = smtplib.SMTP_SSL(smtp_server, port)

try:
    # Authenticate (if required)
    smtp.login("your_username", "your_password")

    # Send the email
    smtp.sendmail(sender, receiver, message.as_string())

finally:
    # Close the connection
    smtp.quit()

If the error persists, make sure you've correctly instantiated the `SMTP_SSL` object and are using the correct method call (`sendmail()` instead of `sendemail`). If there's a custom `sendemail` function, it might be from a third-party library or a custom implementation outside the standard `smtplib`.
