当 AWS SES 出现限流故障时，会引发 smtplib.SMTPServerDisconnected 异常。因此，建议在使用 AWS SES 发送邮件时，需要包含对此异常的处理逻辑。示例代码如下：

import smtplib
from botocore.exceptions import ClientError

def send_email(subject, body):
    try:
        # Connect to the SMTP server using AWS SES
        smtp_server = smtplib.SMTP("email-smtp.us-west-2.amazonaws.com", 587)
        smtp_server.ehlo()
        smtp_server.starttls()
        smtp_server.login("AWS_SES_SMTP_USERNAME", "AWS_SES_SMTP_PASSWORD")

        # Create the message
        message = f"Subject: {subject}\n\n{body}"

        # Send the message
        smtp_server.sendmail("sender@example.com", "recipient@example.com", message)

    except smtplib.SMTPServerDisconnected as error:
        # Handle the case when AWS SES throttles your emails
        print(f"AWS SES throttling failure: {error}")

    except ClientError as error:
        # Handle other AWS SES errors
        print(f"AWS SES error: {error}")

    except Exception as error:
        # Log any other errors
        print(f"Error: {error}")

    finally:
        # Close the SMTP server connection
        smtp_server.quit()

# Send an email
send_email("Test email", "This is a test email.")
