    Default DNS problem?: local delivery: status=deferred

    Hello, after adding a second DNS (298.67.220.220) to my resolv.conf:

    nameserver localhost # bind9 is installed
    nameserver 208.67.220.220 # open dns server

    I have the following problem in the zimbra.log:

    May 20 07:08:22 vmx-ext-fi-1 postfix/lmtp[6997]: 5DBF32F2646: to=<username@mydomain>, relay=none, delay=34212, delays=34022/0.11/189/0, dsn=4.4.1, status=deferred (connect to vmx-ext-fi-1.mydomain[67.215.65.132]:7025: Connection timed out)


    67.215.65.132 is not my public IP address but it is open DNS!!

    As a result mail is not delivered to mailboxes and all messages remain in the deferred queue.

    What is to blame? my configuration or Open DNS?
    I added the second DNS Server because with 'localhost' I cannot 'dig zen.spamhaus.org'. (I'd like to solve this issue too but I don't know how)
    Is it correct to add a second DNS server in a ZCS installation?
    What is the best practice?
    Thanks
    Simone

    Hello, it looks like an Open DNS problem. I've found threads on the Internet about this problem. They redirect invalid queries to search pages. I have the same problem from windows: nslookup resolves zen.spamhaus.org to an IP belonging to Open DNS!. I'll never use them again.
