Python发送邮件给多人

import smtplibfrom email.mime.text import MIMETextmail_host = 'smtp.gmail.com'mail_user = '[e-mail]'mail_pwd = 'xxxx'def send_email( content, mailto, get_sub ):    print 'Setting MIMEText'    msg = MIMEText( content.encode('utf8'), _subtype = 'html', _charset = 'utf8')    msg['From'] = mail_user    msg['Subject'] = u'%s' % get_sub    msg['To'] = ",".join( mailto )        try:        print 'connecting ', mail_host        s = smtplib.SMTP_SSL( mail_host, 465 )                        #s.connect(mail_host)                print 'login to mail_host'        s.login(mail_user, mail_pwd )                print 'send email'        s.sendmail(mail_user, mailto, msg.as_string())                print 'close the connection between the mail server'        s.close()    except Exception as e:        print 'Exception: ', eto_list = [ '[e-mail]', '[e-mail]' ]send_email( 'hello', to_list, 'hi xxx')

我的测试程序使用gmail的smtp服务器， 多人的列表使用list存储

备注：有时候发送的时候会报gmail的密码错误，可能是由于您开通了两步认证，使用应用程序密码就可以了
