Python利用smtplib实现邮件发送

import smtplib, ssl

smtp_server = "smtp.163.com"
port = 465# 对于TLS连接，我们使用465端口。 

# -*- coding: utf-8
import smtplib
# 邮箱服务器相关配置
smtp_server = 'smtp.163.com'
smtp_port = 465
# 发件人相关配置
mail_sender = 'liululee@163.com' # 发件人电子邮箱
mail_sender_password = 'XXXXXXXXXXXXXXXXXXX' # 发件人邮箱密码
# 建立到邮件服务器的加密连接
server = smtplib.SMTP_SSL(smtp_server, smtp_port)
server.login(mail_sender, mail_sender_password)
# 邮件内容
receiver_email = "729235361@qq.com"
message = "\n".join([

    "To: {}".format(receiver_email),
    "From: {}".format(mail_sender),

# 发送邮件
server.sendmail(mail_sender, receiver_email, message)

# 1.创建邮件对象
message = MIMEMultipart()
# 2.设置邮件主题
subject = Header('来自poycode.cn的晚安问候', 'utf-8').encode()

# 3.设置发送者
message['From'] = mail_sender
# 4.设置接收者
message['To'] = receiver_email
# 5.设置抄送者
message['Cc'] = 'developlee@163.com'
# 6.添加文字内容
## 6.1 普通文字
text = MIMEText('Hi, 欢迎你访问我的个人站点 poycode.cn ', 'plain', 'utf-8')
message.attach(text)
## 6.2 超文本内容
# 添加html内容
