Sendmail Deffered Error?

I have sendmail configured on my Fedora 9 Box.I tested with:
#sendmail -d0 < /dev/null
It displayed machine name as successfully
But when I ran:
echo "hello root" | mail -v -s hello
It Showed me Mail deffered Error.
Is it under Firewall of the company.

Did the error message state exactly why the message was deferred? For example, sendmail on your box may not have been able to connect to the remote SMTP server. It's possible that your corporate firewall is blocking outgoing connections on port 25 to prevent spamming by infected machines on the network. You may need to have sendmail relay outgoing mail through your company's mail server or ask for an exception to be made in the firewall policy. But we need a little more information (and you should probably talk to your firewall or e-mail administrator if you suspect outgoing traffic is being blocked).
