使用 python 3.7.3 发送带附件的电子邮件

Question

我正在使用 python 3.7.3 运行 python 脚本。下面是代码。这没有做任何事情。它只是显示消息“已发送电子邮件”，实际上并不发送电子邮件。

此代码以前用于 Python 2.7，只是将“multipart”更改为“Multipart”。我不得不将 M 更改为 m，因为它会引发错误。现在，它不会抛出该错误。

我已检查机器上的 telnet 是否已启动。

telnet localhost 11
Trying 111.1.1.1.......
Connected to localhost.
Escape character is '^]'.
220 abcdef.com ESMTP Exim 4.92 Tue, 09 Nov 2021 11:19:10 -0500
quit

 telnet
telnet> quit

请帮忙。提前谢谢你。

#Send email with attachment

sender = 'abc@test.com'
receivers = 'xyz@test.com'



msg = email.mime.multipart.MIMEMultipart()
msg['Subject'] = 'Test script'
msg['From'] = 'abc@test.com'
msg['To'] = 'xyz@test.com'


# The main body is just another attachment
body = email.mime.text.MIMEText("""Please find the updated data in attached csv""")
msg.attach(body)

# CSV attachment
filename='/home/abc/python_scripts/test.csv'
with open(filename, "rb") as fs:
    part = MIMEBase('application', "octet-stream")
    part.set_payload(fs.read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment', filename=os.path.basename(filename))
msg.attach(part)

try:

    server = smtplib.SMTP('localhost',11)
    server.sendmail(sender, receivers, msg.as_string())
    server.close()

    print('Email Sent')

except SMTPException:
    print('Something went wrong...')

上面的脚本工作得很好。似乎服务器未正确设置以从“@test.com”发送电子邮件。 请随意在您的脚本中使用上述代码。
