使用python smtplib 模块发送邮件

#coding:utf-8    
import smtplib   
from email.mime.text import MIMEText
from email.utils import formataddr


class Mail():

    def __init__(self, receiver_emails, sender_email="*******@163.com", sender_passwd="******"):
        self.sender_mail = sender_email    # 发件人邮箱账号

        self.receiver_emails = receiver_emails   # 收件人邮箱
        
    def send_mail(self, email_title, html_msg):
        ret = True
        try:
            msg = MIMEText(html_msg, 'html', 'utf-8') # html格式的内容
            msg['From'] = formataddr(["franklin", self.sender_mail])   #  发件人邮箱昵称、发件人邮箱账号
            msg['To'] = ",".join(self.receiver_emails)   # 收件人邮箱账号
            msg['Subject'] = email_title  # 邮件的主题  
            server = smtplib.SMTP("smtp.163.com", 25)  # 发件人邮箱中的SMTP服务器，端口是25
            server.login(self.sender_mail, self.sender_passwd)    
            server.sendmail(self.sender_mail,  self.receiver_emails, msg.as_string())   #发件人邮箱账号、收件人邮箱账号、发送邮件
            server.quit()    
        except Exception as e:
            print(e)
            ret = False
        return ret

if __name__ == '__main__':

    to_users = ['1**********@qq.com', '*********@qq.com']  # 收件人邮箱账号  

    mail_title = "思南新闻6666"
