使用python 3实现发送邮件功能

import smtplib
from email.mime.text import MIMEText
SMTPsever="smtp.163.com" #邮箱服务器
sender="**********@163.com" #邮件地址
password="Whl3386087" #密码
receivers=["********@qq.com"]
content = '端午节快乐哈哈 \n         邮箱轰炸机的问候'
title = '端午节问候' # 邮件主题
message = MIMEText(content, 'plain', 'utf-8') # 内容, 格式, 编码
message['From'] = "{}".format(sender)
message['To'] = ",".join(receivers)
message['Subject'] = title
# mailsever=smtplib.SMTP(SMTPsever,25) #服务器端口
# mailsever.login(sender,password)#登陆
try:
 mailsever = smtplib.SMTP_SSL(SMTPsever, 465) # 启用SSL发信, 端口一般是465
 mailsever.login(sender, password) # 登录验证
 mailsever.sendmail(sender, receivers, message .as_string()) # 发送
 print("mail has been send successfully.")
except smtplib.SMTPException as e:
  print(e)
mailsever.quit()
print("OK")
