一直收到自己寄給自己的垃圾信
最近一直收到自己寄給自己的垃圾信,怪的是連查看電子郵件信箱真的也是自己的,可是確定沒有自己寄給自己,排除電腦中毒現象,請問有沒有那位前輩遇過,該問題mail server該如何防堵呢? 感謝!可是權限不夠...我也依職受到偽造信困擾最近還發生實際詐騙.... 用這招POP Before SMTP

公司目前也是一直有這問題存在，受教了 謝謝 以前碰到過。如果自己沒中毒的話，那可能就是你的朋友中毒或被垃圾客拿來利用。
你可以檢查一下 SMTP IN 的 Log，看看這些信是否來自外部。 我近日也是一直收到自己的垃圾郵件 , 查過是從外面假冒的 ,鎖 IP (189.106.87.81) 過幾天他又換一個 ...
應該可以用DNS-BL來封鎖 , 但開DNS-BL會有 2-3 個客人的信會進不來 . 真的很煩 !!!
還有其他方法嗎 ?

Fri 2008-12-26 03:02:46: ---------- 我的mail server 一直有設定 pop before Smtp
還是一直出現 自己寄給自己的垃圾郵件 ... 那再加上這一招：
IP Shielding (防護罩) 抵禦偽造信件 已經成功擋住 !!! 感謝 !!!原因真的是POP before SMTP ....
我之前有參改MarchFun'r的說明來設定 ,可能是多次改版而被修改:
在POP before SMTP 的設定下的四個選項 都被打勾,
只要將第 3 個:
Don't apply POP Before SMTP to messages sent to local accounts, 打勾取消就ok !
我也找到被擋下垃圾信的Log , 如下 :xxxx must check for new mail first

Don't apply POP Before SMTP to messages sent to local accounts, 打勾取消
表示寄給本地帳號的信不要套用 POP Before SMTP，這樣不是讓垃圾郵件更容易進來嗎？為什麼之前開啟了 POP Before SMTP 後還有信可以假冒，有可能是因為在那之前不久你剛好收過信？ 8# MarchFun
沒有錯la ..... Don't apply POP Before SMTP to messages sent to local accounts 英翻中:
當郵件發送到本地帳戶不適用 POP Before SMTP ,
打勾代表 送給 Local User不用 POP Before SMTP
不打勾 送給Local User 是要 POP Before SMTP 9# shem888
