python发送邮件实例 - 使用smtplib模块

# 导入 smtplib 和 MIMEText
import smtplib
from email.mime.text import MIMEText
    
# 定义发送列表
mailto_list=["root@pythontab.com","10118157@qq.com"]
    
# 设置服务器名称、用户名、密码以及邮件后缀
mail_host = "smtp.163.com"
mail_user = "xx@163.com"
mail_pass = "xx"
mail_postfix="163.com"
    
# 发送邮件函数
def send_mail(to_list, sub, context):
    '''''
    to_list: 发送给谁
    sub: 主题
    context: 内容
    send_mail("xxx@126.com","sub","context")
    '''
    me = mail_user + "<"+mail_user+"@"+mail_postfix+">" 
    msg = MIMEText(context)
    msg['Subject'] = 'python email test'
    msg['From'] = sub
    msg['To'] = ";".join(to_list)
    try:
         send_smtp = smtplib.SMTP()
         send_smtp.connect(mail_host)
         send_smtp.login(mail_user, mail_pass)
         send_smtp.sendmail(me, to_list, msg.as_string())
         send_smtp.close()
         print 'success'
        return True
    except (Exception, e):
         print(str(e))
         print 'false'
  send_mail(mailto_list,"test mail","你好")
