If this is behind a NAT router (or firewall) you should only have one DNS server in your resolv.conf (the DNS server that has your Zimbra records) and you should also have the following:
Code:
search yourdomain.com
If it's not behind a NAT router is it on a public IP? Please also run the 'host' command I asked you for earlier. Otherwise everything looks OK. What problems do you have? Have you looked in the
log files for any errors?
