fc1 email does not work?

[Hongwei Li]

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!
