这样什么含义?

hpaps@/ -# Jan 22 23:02:16 hpaps sendmail[18727]: unable to qualify my own domain name (hpaps) -- using short name

Jan 22 23:09:31 hpaps sendmail[18927]: unable to qualify my own domain name (hpaps) -- using short name

机器上突然显示的信息,说什么主机名之类的不懂,
我看/etc/hosts是对的呀:
# The form for each entry is:
# <internet address>;    <official hostname>; <aliases>;
# For example:
# 192.1.2.34    hpfcrm  loghost

10.85.17.10     hpaps   hpaps

那这是什么信息呀???可能不要紧的吗？

还是没用
我改了/etc/hosts:
10.85.17.10 hpaps

然后现在又出现了：
hpaps@/var/adm -# Jan 23 02:03:37 hpaps sendmail[26538]: unable to qualify my own domain name (hpaps) -- using short name


到底我哪里设置的有问题呀，真不清楚？？？？？？
