Python AWS SendRawEmail操作：来自多个收件人的非法地址错误

我有一个AWS Lambda，它使用SES发送电子邮件。当我只有一个收件人时，此函数起作用。但是，只要我向数组中添加2个或更多收件人，它就会失败，并出现以下错误

我在一个沙箱环境中，看到我必须验证发送到的电子邮件域。因此，这不再是一个问题

"An error occurred (InvalidParameterValue) when calling the SendRawEmail operation: Illegal address"

我的职责如下：

def send_email(sender, recipients, aws_region, subject,url):
    
    client = boto3.client('ses', region_name=aws_region)
    
    BODY_TEXT = "Hi"
    BODY_HTML = """\
    <H1>Your Results have been process</h1>
    <br>
    {!s}
    </br>
    """.format(url)
    
    msg = MIMEMultipart('mixed')
    msg['From'] = sender
    msg['To'] = ", ".join(recipients)
    msg['Subject'] = 'TOI Order Alert'
    
    # The character encoding for the email.
    CHARSET = "UTF-8"
    
    msg_body = MIMEMultipart('alternative')
    textpart = MIMEText(BODY_TEXT.encode(CHARSET), 'plain', CHARSET)
    htmlpart = MIMEText(BODY_HTML.encode(CHARSET), 'html', CHARSET)
    
    
    # Add the text and HTML parts to the child container.
    msg_body.attach(textpart)
    msg_body.attach(htmlpart)
   


    # Attach the multipart/alternative child container to the multipart/mixed
    # parent container.
    msg.attach(msg_body)
    
    # Add the attachment to the parent container.
    # msg.attach(att)


    
    
    # Provide the contents of the email.
    response = client.send_raw_email(
            Source=msg['From'],
            Destinations=[
                msg['To']
            ],
            RawMessage={
                'Data':msg.as_string(),
            }
        )
        
    return("Email sent! Message ID:", response['MessageId'])

下面所示的通过收件人对我来说很有用。您可以在代码中尝试相同的方法：

response = client.send_raw_email(
            Source=msg['From'],
            Destinations= recipients ,
            RawMessage={
                'Data':msg.as_string(),
            }
        )

response = client.send_raw_email(
            Source=msg['From'],
            Destinations= recipients ,
            RawMessage={
                'Data':msg.as_string(),
            }
        )
