Thu 2009-02-12 14:08:41: ---------- 發信附帶附件和 "500 What? I don't understand that." 沒有關係。請檢查系統設置。 能否再明确一些,是检查服务器端的设置,这封邮件是个别现象,希望通过这个故障来学习邮件排错的技巧 这个提示有点奇妙 呵呵，真生动阿。
能否总结一下更多的特征？ 比如自己发给自己？ 内部收发？ 外部收发等 在内部中使用,用于群发,单独发的时候也出现过,而且是随机的 原帖由 fsdjsb 于 2009-2-13 14:34 发表 http://www.5dmail.net/bbs/images/common/back.gif

我在去年 8 月 10 遭受所謂「駭客（實際上不是駭客，而是一批只是想學做駭客的搗蛋鬼）」攻擊，一天發了將近 900 封 mail 給我，連續二天，但都被我拒收了，其所發之 mail 中並未附有任何附件，然而我的日誌中也出現好幾次 500 What? I don't understand that.，那是發信人系統的問題，以此提供參考。 是不是收件人太多 了 原帖由 redif 于 2009-2-14 10:57 发表 http://www.5dmail.net/bbs/images/common/back.gif

不太清楚是不是收件人太多關係，但肯定是發信人系統上的問題，因為平時我的 SMTP(in) 的日誌裡從來不曾有過這樣的顯示。 這個日誌有沒有被改動過, 邏輯上有不對的地方 !! 原帖由 leungys 于 2009-2-14 16:01 发表 http://www.5dmail.net/bbs/images/common/back.gif

我貼出一段，我被假冒「駭客」想以我的主機作為他濫發垃圾廣告郵件的跳板時內有 "500 What? I don't understand that." 的 SMTP(in) 日誌：
