sendmail appears to be installed but couldn't start service
Hi,I tried to start sendmail but had failed
[root@vps sbin]# which sendmail
/usr/sbin/sendmail
[root@vps sbin]# service sendmail start
sendmail: unrecognized service
I had tried "chkconfig sendmail on",but the same problem still persist.
Anyone here could give me some idea why is this happened?
Thank you
