Sendmail Unknown Host and world writable issue
 
Can't start sendmail without the following errors:
Code:
/etc/init.d/sendmail start
 * Starting Mail Transport Agent (MTA) sendmail                                hostname: Unknown host
451 4.0.0 /etc/mail/sendmail.cf: line 106: fileclass: cannot open '/etc/mail/local-host-names': World writable directory
                                                                        [ OK ]
As you can see, /etc/mail/sendmail.cf IS writable...
Code:
/etc/mail# ls -la

Hi,

To get rid of the unknown host warning add a name for your box in /etc/hosts.
Regarding the world writable issue, you have to make sure, that /etc and /etc/mail are not world writable.
If you want, you can bypass the warning using the DontBlameSendmail option, but I suggest you to try to find the real cause of the problem.

Regards
