    Default Getting deferral errors from one host only, how can I figure out why?

    message deferral detail
    -----------------------
    smtp (total: 32)
    32 Host not found, try again

    no MX host for amsinet.com has a valid address record

    This is our old website we used we are currently switching over to a new domain and using zimbra. A lot of people are not moved over yet and i'm getting a few deferral messages.


    dig amsinet.com mx

    ;; MSG SIZE rcvd: 116


    How can I find out if this is on my end or theirs?
    What other log files should I be checking?

    Also my log says I have 12 bounced messages how can I check which messages bounced? and why?

    Go to the Split DNS article and run (on the Zimbra server) all the commands in the 'Verify....' section of that article and post the output here.

    Everything seems find and its only to the Fusemail.net domain that it hangs.
    This is the error I am getting

    1E9B241DB9 - This is the ID
    Host or domain name not found. Name service error for name = mx.fusemail.net type=a: host not found, try again.

    This is the dig to my mail server

    [Bash] Mail1 - Pastebin.com

    This is the dig to the old domain

    [Bash] Mail2 - Pastebin.com

    Only emails to that domain hang and its not all the time we send hundreds a day only a few hang..

    Pastebin seems to be down right now

    I asked you to run all the commands in that section of the article, you've missed some of them - please run the commands you've missed.

    BTW, you made the following comment in your previous post:

    You haven't provided any dig output for that domain. I suggest you run the dig commands again (on the Zimbra server) for that domain and also the other commands that we need to see.
    Regards

    Your hosts file is incorrect, the loopback line needs changing - full details of what that should contain are in the Split DNS article (and many, many, forum threads).

    When you provide information in response to a question can you make sure you provide all the output from a specific command (including the specific commands you used). The dig output is incomplete for this command:

    Code:
    dig fusemail.net mx
    It doesn't show the last part of it the specifies which DNS server was used. It does (assuming it's using the LAN DNS server), however, show that you have the Public IP address for the A & MX records instead of the LAN IP.

    Fix those two problems and try the tests again to check that you've corrected the problem.
    Regards

    Okay, think I might have it now.

    Now should my resolv.conf also be changed?

    cat /etc/resolv.conf
    domain amsi2.com
    search amsi2.com
