Python发送邮件给多人

import smtplib
from email.mime.text import MIMEText

mail_host = 'smtp.gmail.com'
mail_user = '[email protected]'
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: ', e


to_list = [ '[email protected]', '[email protected]' ]
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
