执行  cat /etc/resolv.conf

将结果贴出来看看

回复 2# dengbao2001


  [root@STCS mail]# cat /etc/resolv.conf
#nameserver 192.168.51.11
search localhost.localdomain

本人水平有限，觉得你的DNS服务器配置有问题

配置一个 可以解析你外发域名的DNS服务器

ressolv.conf 内容如下

nameserver x.x.x.x # x.x.x.x 为DNS服务器ＩＰ地址

按照你的方法我增加了
#cat /etc/resolv.conf
nameserver 192.168.71.11
nameserver 192.168.71.41
domain simplo.com.cn
search localhost.localdomain

再次发mail 又出现
Feb 10 11:32:00 STCS sendmail[18903]: My unqualified host name (STCS) unknown; sleeping for retry

用nslookup 配合你设定的DNS服务器解析下你需要发邮件的域名，看看是否可以解析到MX记录

是这样吗？
[root@STCS log]# nslookup simplo.com.cn
Server:         192.168.71.11
