So from the CentOS box you can type something like: host -t mx domain.com and that works? How about this from the Windows box: c:\>nslookup > server YourCentOSName or IP > set type=mx > yourdomain.com That should work If that also works, then check the DNS server your windows box is using. It may have cached the DNS entry for domain.com (assuming the DNS server is NOT the CentOS box) You could also try an ipconfig /flushdns Shawn
