代码如下：

#!/usr/bin/python3

import smtplib

from email.mime.text import MIMEText

from email.header import Header

sender = 'from@runoob.com'

receivers = ['429240967@qq.com'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码

message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')

message['From'] = Header("菜鸟教程", 'utf-8')

message['To'] = Header("测试", 'utf-8')

subject = 'Python SMTP 邮件测试'

message['Subject'] = Header(subject, 'utf-8')

try:

smtpObj = smtplib.SMTP('localhost')

smtpObj.sendmail(sender, receivers, message.as_string())

print ("邮件发送成功")

except smtplib.SMTPException:

print ("Error: 无法发送邮件")

报错如下：

是不是因为没有安装sendmail的问题，望大神能给与解决
