    Default The problem is back

    I don't know what has changed. I went through everything that has been suggested thus far but the problem keeps popping up. This really odd thing is that it started when I put it behind the firewall. The hosts file was corrected in accordance with what has been put here. There is no public IP though in there, which concerns me. It APPEARS that internal messages are being delivered, but anything on another domain is deferred. I just made a deal for this server to host a business domain so I really need some help here.

    ::UPDATE:: - Ok, this one is weird. When I have "Enable DNS Lookups" checked on that server, I can send mail, but cannot receive. When it is not checked, I can receive mail, but I cannot send it. I just did a number of test messages including Comcast.net and Yahoo.com domains and when I toggle that checkbox off and on, it looks like a functioning e-mail server. Unfortunately, I don't have the time to sit here and toggle that checkbox lol.

    Default Error Message

    I'm getting the error message "host or domain name not found" in the deferred queue now. That is with DNS lookups enabled.

    Without them enabled, I get a "connect to comcast.net[76.96.54:13]: connection timed out. 1 messages."

    It would appear that messages are only sent and/or received about 1% of the time. I'm open to any suggestions that could get me back to a working server. Preferably without a reload.

    Which firewall are you using? Can you telnet from your Zimbra server to port 25 on the server that fails? Post the output again of the following commands:

    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    dig yourdomain mx
    dig yourdomain any
    host `hostname` <- use backticks not single quotes
    Regards

    Not sure if the following is what you're looking for. I used the hostname of the box. The hostname is not really box, I'm just trying to keep some stuff confidential.

    Code:
    root@box:~# host 'box'
    box has address 208.69.36.132
    Host webmail not found: 3(NXDOMAIN)
    As I'm sure this matters, the output of that last command did not output my static IP address. I don't know what that IP address is.
    Oh, and the firewall is Endian

    Your dig commands are incorrect, they should be for the domain name not the FQDN of your server i.e.

    Code:
    dig bcrockford.com any
    dig bcrockford.com mx
    and the host command should be exactly as I asked you for in the lost post:

    Code:
    host `hostname`  <-- do not modify or add anything to that command use it as-is
    Are you using any of the SMTP proxy or inspection on the EFW? Is the EFW just set for the RED interface or GREEN as well?

    I also asked if you can telnet from the Zimbra server to port 25 on the mail server of a failing host?
    Regards

    EFW is not doing anything with SMTP or anything to do with the mail server. I have triple checked and it is configured with 1:1 NAT to the correct public IP and configured to allow all outgoing traffic. Everything there should be working correctly.
    Hopefully, this is what you're looking for.

    Your A record should point to the LAN IP of your Zimbra server not to the Public IP.

    Well, I did this now. It should take a few hours to propagate though, I assume. So we'll see what happens. Weird thing though, when I do an nslookup, I get the following:

    Code:
    Server:  resolver1.opendns.com
    Address:  208.67.222.222
    
    Non-authoritative answer:
    Name:    mail.bcrockford.com.localdomain
    Address:  208.69.36.132
    Besides the obvious weird output of localdomain, that's not my public IP address.

    I have made sure that the DNS resolves to the LAN IP, which it is now. I then attempted to get to my web page, it did not go. It just timed out.

    Was that done on the Zimbra server?

    Sorry, that was my mistake. You need an A record for your mail server and the records should look like the following ones:

    Code:
    bcrockford.com.        604800  IN      A       PUBLIC IP ADDRESS
    mail.bcrockford.com.        604800  IN      A       192.1.1.10
