不存在的用户发送大量垃圾邮件
斑竹，好久没来了，圣诞快乐。言归正传
最近，发生了好几次，发现邮件服务器向外大量发送垃圾邮件，上万封，发送者为<>或者我服务器中不存在的一个用户名称，
在Mail Relay Options中我已选了No Mail Relay,还勾选了check valid sender,Atuo-deny possible hack attempts,Disable SMTP 'VRFY' command 3项
我始终就没找到关于发信者禁止为空的选项
我的机器是2003+mail8.22+FTP，没有网站.
还有一件怪事，也发生过两次了，早晨收邮件，客户端无法连接服务器，远程登录服务器，发现pop3，什么的一切都在运行，手动重启服务，还是依旧。web登录没有问题，
检查邮件服务器的端口，也没有被其他程序占用。等过个一个小时，有都正常了。令人百思不得其解。:Q 我把日志分析贴上来，斑竹把我看看，有一个和我差一个字母的域名在作怪！！！

16,384,603 4,151 我的域名 一开始，我以为是我的用户被人利用了，可仔细查看，发现大量发送邮件的用户的域名和我的域名差一个字母，可这个用户
怎么能利用我的邮件服务器向外发邮件呢？虽然是失败，但大量的待发邮件挤在我的队列里，实际上使我的服务器完全被阻塞了。
为什么会发生这样的事？:Q 这个应该是退信式的垃圾邮件吧 你的有帐号被利用在发送垃圾邮件了 需要分析日志 然后回溯查询被利用的帐号 原帖由 lgj858 于 2010-12-23 11:20 发表 http://bbs.5dmail.net/images/common/back.gif
你的有帐号被利用在发送垃圾邮件了
斑竹，帮我看看日志，好像不是我的账户被利用啊
我的邮件账户很少，就3个用户，一个备份邮箱用户。能帮我看看是哪个用户被利用了吗？ 要看他验证的用户 用的哪个 原帖由 lgj858 于 2010-12-24 10:19 发表 http://www.5dmail.net/bbs/images/common/back.gif
要看他验证的用户 用的哪个
斑竹，日志分析上看的出来吗？通过看日志分析，反查日志是吗？ 当然有记录
