python 利用 tls验证的方式 发送邮件

根据MSSQL数据库查询结果，判断发送邮件内容

    msg=email.mime.multipart.MIMEMultipart()
    msg['From']=form_adder
    msg['To']=','.join(to_adder)
    print(msg['To'])
    msg['subject']='new zabbix problems notice'
    content = conent
    txt = email.mime.text.MIMEText(content, 'plain', 'utf-8')
    msg.attach(txt)

        server.quit()
    except Exception as e:
