上面是syslog中的sendmail的错误信息，从log中可以看出错误的原因是hostname和domainname的问题。由于sendmail 默认先查找fully qualified hostname，从而得到domainname。但我设置hostname为solaris，sendmail没法得到完整主机名，只能使用 solaris这个短主机名。这就是上面日志的出错信息的含义。
知道出错的原因，就知道如何解决问题的方法。在solaris中，我们只需修改/etc/hosts文件，加上完整主机名就可以了。例如，我原来的/etc/hosts文件内容如下：
::1 localhost 127.0.0.1 localhost 192.168.11.11 solaris loghost |
修改成：
::1 localhost 127.0.0.1 localhost 192.168.11.11 solaris solaris.localhost.localdomain loghost |
这样，solaris中的sendmail就不会出现上述错误。我们可以用sendmail命令查看是否成功：
% /usr/lib/sendmail -d0.1 -bt < /dev/null |
-d0.1是debug的等级，-bt是地址测试，</dev/null是输入重定向。

另外，我们还可以用以下的脚本进行测试：
/usr/lib/mail/sh/check-hostname |
修改前：
Hostname solaris could not be fully qualified. We recommend changing the /etc/hosts entry: 192.168.11.11 solaris loghost to: 192.168.180.10 solaris solaris.localhost.localdomain loghost |
修改后：
Hostname solaris OK: fully qualified as solaris.localhost.localdomain |
