枫下家园 / 电脑用户 / 紧急呼叫：温柔杀手--退隐江湖，阿土，我们公司的mail server(linux)不可以pop收信和发信了，但是web收发都正常，到底是怎么回事，还是firewall的问题吗？这些天搞的要疯掉了，估计老板没多久就要炒了我了，wu.....从昨天开始是不可以发信，今天就收都收不到了。我查了一下，mail server 上的log文件都没有了，一个faillog, lastlog都是乱码，老板还不让我改密码，怎么办？ -xiaodongxi(xiaodongxi); 2002-3-8 {202} (#394526@0)

信息比较少，难以定位。sendmail一般来说很稳定，但看样子是sendmail和pop3停掉了，最简单的办法是reboot。另外查一下是否open relay，被当作垃圾邮件转发站也能累死server的。anything else? -mildkiller(); 2002-3-8 (#395495@0)

需要更详细的relay信息，最好xiaodongxi把发件失败的提示信息和邮件头放上来看看 -heian(㊣黑暗天使); 2002-3-8 (#395518@0)

web mail可以不用pop取邮件的,直接读文件就可以了。有可能是popd死了或者验证有问题。 -netee(netee); 2002-3-8 (#395532@0)

faillog and lastlog are binary files, you'll need to use lastlog(8) and faillog(8) to examine the content. Let me ask you some questions first:1. which linux distribution are you using? I'd assume Redhat?

2. what's the output of 'ps ax | grep sendmail'?

3. what's the output of 'ps ax | grep pop'?

4. what's the output of 'lsof -i -n' (assuming you have lsof installed)?

5. when you say "mail server 上的log文件都没有了", what does that mean? Are you missing all the log files or only the maillog?

BTW, I hate sendmail and stay away from it as much as possible :-) -dennis2(Dennis); 2002-3-9 {448} (#395710@0)
70% because pop3d is dead try "kill -1 1" to restart pop3d in inetd.conf file if it is not commented -ghyll(阿土); 2002-3-9 (#395754@0)

关于我们公司服务器的问题我以前请教过各位专家，但是由于小女子对LINUX 实在是一窍不通，要处理也无从下手。公司里有四个服务器，其中 -xiaodongxi(xiaodongxi); 2002-3-9 {1392} (#395882@0)

qmail 是和 sendmail 类似的 mail server, 有时候因为大量 email 的涌入，qmail-pop3d 会死掉，首先杀掉 qmail-pop3d 再运行试试。 -violent_panda(暴力大熊猫); 2002-3-9 (#395912@0)
You still need to find the log file before you can solve the problem ... -dennis2(Dennis); 2002-3-10 {1872} (#396815@0)

thanks everyone's help! I'll have a try. -xiaodongxi(xiaodongxi); 2002-3-10 (#397226@0)
