Hi, We have a fc1 on a new dell pc, 3GHz, 1GB ram. Suddenly, in a few minutes ago, people cannot access email from any pop3 mail tools: outlook, squirrelmail, etc. Only pine can work, but also shows warning: Can't lock for write: /tmp must have 1777 protection then, it shows: Folder vulnerable: directory /var/spool/mail must have 1777 protection. I did not change anything after fc1 is installed a few weeks ago. Should I change the permission of /tmp and /var/spool/mail? How to do it? Any other things I must do? Please help!!! Thanks!
