有时候需要将数据库中的统计信息统计好之后，直接每天定时发邮件。
可用python脚本写好逻辑后，使用crontab每天定时执行

msg['Subject'] = "本月****来源的订单"
msg['to'] = mailto

body = MIMEText(content)
msg.attach(body)
smtp = smtplib.SMTP('mail.163.com')
smtp.sendmail(sender,mailToList,msg.as_string())
smtp.quit()
except smtplib.SMTPException, e:
print "error...%d: %s" % (e.args[0], e.args[1])
if __name__=="__main__":
content=queryDBdata()
send_mail(content)
其中crontab -e 编辑表达式
