    Default Split DNS?

    I don't think that should be the problem. We have no problems sending mail. A I know that mail from yahoo, gmail, and cox accounts can get in. It looks like the only problem is with the domain of our soon-to-be-bosses/coworkers on the same class b network.

    Heck I'll attach a somewhat less edited version of the dig reports

    DNS looks right.

    I know there is a log that will tell you exactly why the mail is being rejected. I use webmin to view logs so I'm not sure which log file in the Zimbra/logs folder it is.

    Default Log extract

    Bill, thanks for sticking with me on this.

    Phoenix, if you are still looking in. as far as I could tell there were no problems with our setup (no split dns) as mail was working in both directions except for this one sender, which is part of the reason I'm confused.


    This is from /var/log/zimbra.log

    firewall.sb.state.State.us - if this is the rejected server you are talking about, the name doesn't match the records from the DNS info you posted earlier.

    In the above, "firewall" is the host and "sb.state.State.us" is the domain. Plus the domain in your prior post is "state.UsState.us".

    Thus these records aren't being found.

    Default Firewall

    Bill,

    What is rejecting is either "UsState-exch0.UsState.gov" or "user@UsState.gov", I can't tell from the message.

    firewall.sb.>>>>> is the firewall between zimbra and public internet and is doing NAT.

    I have an entry for it in my /etc/hosts file on zimbra

    10.168.30.1 firewall.sb...... firewall

    ALL e-mail passed through that server to get to the DMZ servers which are all on the 10.168.30.0/24 network

    I don't see an A record in the DNS info that you posted for that host. That is why it is being rejected.

    If they can't setup an A record add that IP to your trusted networks in the Admin GUI.

    Do they need an a record for the *-exch? servers?

    If it is sending mail as a mail server then it needs an MX record and an A record.

    It looks like the MX record for that domain is pointing to "mail" and "mail" also has an A record. If they are using another mail server "exch" or what ever then it needs an MX record as well as an A record.

    Or I think you can ad the IP to the trusted networks parameter.

    You might even get away with adding the IP and host to your Hosts file. Not sure about that.

    Default May have it there.

    Bill,
    I'm going to try to get the owners of UsState-exch0.UsState.gov to get it setup in dns

    Thanks for your help. I'll update if I get them to make the change, and it works.

    James
