fileclass: cannot open '/etc/mail/local-host-names sendmail

fileclass: cannot open '/etc/mail/local-host-names sendmail

problem

sendmail is not working. Giving the error '/etc/mail/sendmail.cf: line 91: fileclass: cannot open '/etc/mail/local-host-names': World writable directory'.

Solution

1). Edit the file /etc/mail/sendmail.cf and add -o ('oh') to line 91 and 588 that is change Fw/etc/mail/local-host-names to Fw-o /etc/mail/local-host-names.

2). Similarly edit /etc/mail/submit.cf and add -o to line 544( i think it may differ) that is change Ft/etc/mail/trusted-users to Ft-o /etc/mail/trusted-users.

3). save both files and restart sendmail

Centos: Restore Root password

1. Start your computer
2. At the GRUB prompt, choose the line on your linux and press e
3. Select the second line (the one that starts with kernel ...) with the cursor and press e again to edit it also.

4. Go to the end of the line and add the word single (this also works with the letter s or the number 1 on most distributions, the choice is yours)

5. Press b to boot with these new parameters

The system will boot into single user mode and offer you a command prompt as root without asking any password.

You can then choose a new password and reboot the computer.
