I can't also send email out, in fact all my emails are stuck at the mail que.
One thing is odd, root@cron reports can send email out

I am having same issue!
Did you find fix?

Did anyone get an idea to check the server logs ?

When having some issue with the server service first thing you need to do is to check the server logs if you want to determinate the source of the issue.

to get last 50 lines you can use this command

Code: [Select]

tail -n 50 /var/log/maillog
live monitoring of the log if you want to test

Code: [Select]

tail -f /var/log/maillog
