421 4.7.0 [TS01] Messages from x.x.x.x temporarily deferred due to user complaints - 4.16.55

This error message indicates we are seeing unusual traffic from your IP address, and that emails from your mail server have been generating complaints from Yahoo! Mail users. Please note that this is a temporary error, and your mail server may automatically re-try sending emails at a later time.

If you are seeing this error consistently, we encourage you to provide us with detailed information, including the complete error message you see in your logs, by filling out this form. (Note: Please make sure to select “Getting deferrals due to user complaints” in the form’s dropdown menu.)

只不過公司瞬間來個 @yahoo.com.tw 約 60 多封信..... 就來個 Error Messages, 心裡亂幹一把的 !!

現在炒熱的 3.5G , 對辦公室的網路安全,也莫大的殺傷力 !!

暫時是無解 ?! ..... 各位網管 除行政手段外......

不知是否有解 ?!

今天 Linux Server 在 Service MailScanner restart 的時後出現的...

如題: Unknown HZ value! (5) Assume 100.

目前在 GooGle 中 .......

在此 memo 一下 !!

ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it. This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address. Problem record(s) are:
 
Server 168.95.1.1 reports that it will do recursive lookups.
Server 168.95.192.1 reports that it will do recursive lookups.
Server 168.95.192.2 reports that it will do recursive lookups.

有人有什看法嘛 ?!

有人知道這個東西嗎?!

使用於 Bind DNS 裡面 !!

example

Your domain does not have an SPF record. This means that spammers can easily send out E-mail that looks like it came from your domain, which can make your domain look bad (if the recipient thinks you really sent it), and can cost you money (when people complain to you, rather than the spammer). You may want to add an SPF record before October 1, 2004, the target date for domains to have SPF records in place.

今天索性再把未裝的 Spamassasin 裝起來...

卻碰到如此的問題,...套件相衝

rpm -Uvh perl-Mail-SpamAssassin-2.53-1.i386.rpm
Preparing...                ########################################### [100%]
        file /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/perllocal.pod from install of perl-Mail-SpamAssassin-2.53-1 conflicts with file from package perl-Text-Iconv-1.2-RH80

試著 rpm -e perl-Text-Iconv-1.2-RH80 --> 我用的 RH 8.0
因為上面有裝 OpenWebMail 的套件...

拿掉以後,再安裝
rpm -Uvh perl-Mail-SpamAssassin-2.53.i386.rpm

居然可以...

反過來也是如此....
也就是安裝好 perl-Mail-SpamAssassin , 再安裝 perl-TExt-Iconv 就不行
都出現如下的 Error Messages

EX. sample
file /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/perllocal.pod from install of perl-Mail-SpamAssassin-2.53-1 conflicts with file from package perl-Text-Iconv-1.2-RH80

請問我該如何解決此問題 !!

不好意思,我又要出題目了...請接招...ps.我沒有答案..

我公司有人要架設 M$ ADS , 目前我掌控 DNS ( abc.com )管理大權..

現在問題來了...

有一組人想整合 ,公司內部系統 ex. gb.abc.com ( 其事業處之 sub-domain )
他們卻沒有權力架設 abc.com 因為權力在我這裡

可是我們公司 @abc.com 並沒有架設 M$ ADS , 我又不想架設(因為組織太複雜)
有何方法可以架設成功的...

我初步的構想

1. 我只要我的 DNS 下放 sub-domain gb.abc.com 給其 gb admin 管理就可.
如此可行嗎?!

2. 還是我一定要架設 @abc.com 的 forest functionality ..??

3. 若是 請事業處先行架設 @gb.abc.com ,之後若再架設 @abc.com 之 ADS 可行嗎? 我的意思是以後可以整合在一起??

我可能描述不是很清楚.. 可是我知道可以並行,想聽聽各位的意見?!
