公司里大概每天都有几个邮箱收到上百封这种邮件，还附带一个附件，他们都说没发过邮件，不知道怎么来的投递失败，求教是不是邮件服务器中毒了？

wxhsh 发表于 2011-3-30 10:04:15

典型被盗发了，升级ＭＤ至10以上，开启动态屏蔽，并修改所有弱口令用户密码。偶前一阵刚批量替换好，很辛苦，但只有这方法。

neil.fu 发表于 2011-3-30 11:40:09

服务器被利用，还是加强弱密码管理吧

支持楼上的说法。

请教下怎样批量修改密码？有没有什么方便的方法。。。。。 批量修改只适用ＯＤＢＣ方式存储帐户数据的用户。因为只有在此模式下密码为明名。一条sql语句就完成了。
