I just installed Mandrake 10 on a new machine. During the set-up, I specified "Standard" security level.
I cannot get postfix to run correctly. The error I get is "Resource temporarily unavailable" when it tries to forward mail to external SMTP servers. I believe the problem may be that postfix user (the user that owns and runs many of the postfix daemons and folders) lacks certain priveleges.
I have found other simple commands that give the same "Resource temporarily unavailable" error: If I am not logged in as root and I try something simple like PING, I also get the "Resource temporarily unavailable" message. Only PING from the
root user gets through.
The priveleges for /bin/ping are rwsr-xr-x
I think that many of the basic system files and functions are not allowing anyone but root to run them.
What did I do wrong? How can I fix this?
