Hi All,

I have setup the Zimbra Collaboration Suite 3.1 in Fedora3 first time.
When I test email function, I cannot receive any email from outside.

I got this return message:
----------------------------------------------------------------------
This is the Postfix program at host zimbra.permanent.serveftp.com.

I'm sorry to have to inform you that your message could not

The Postfix program

: Host or domain name not found. Name service
error for name=zimbra.permanent.serveftp.com type=A: Host not found

Final-Recipient: rfc822; testing@permanent.serveftp.com
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; Host or domain name not found. Name service error
for name=zimbra.permanent.serveftp.com type=A: Host not found
-----------------------------------------------------------------------

I have checked all the service is started.
Should I do any other configure for the postfix.

Thank you
