SendMail Error: Unable to qualify my own domain name

Today,Centos 6.5 Linux,yum installs the SendMail, launches, sends the test mail, in the /var/log/maillog file, the error is as follows:

sendmail[20475]: Unable to qualify my own domain name (ajkhuel) – Using short name

So,Google a bit, found to be the problem with the/etc/hosts file:

Original file content:

127.0.0.1localhost

:: 1 localhostlocalhost.localdomain localhost6 localhost6.localdomain6

192.168.8.66 Ajkhuel

Modified content:

127.0.0.1localhost

:: 1 localhostlocalhost.localdomain localhost6 localhost6.localdomain6

192.168.8.66 ajkhuel abc.mail.com

after the modification, restart the SendMail service and the message is sent successfully.
