Send emails from local network to external recipients error

[plastilin]

Hi. Have those configuration:

Zimbra server: IP 192.168.1.5, domain name mail.company.com

Send emails from relay smtp-out.provider.com

If messages are created on server from web interface and send to external recipient, example *@gmail.com - all good, but messages from server example zimbra@mail.company.com have error:

Host or domain name not found=name service error for name=smtp-out.provider.com type=mx: host not found, try again

I have local DNS where i have zone company.com, and have A string mail.company.com 192.168.1.5

This error have when i try to redirect admin mail to external mail...

How i can fix it?

Go to the Split DNS article and look in the 'Verify...' section and post the information from those commands here, you should also post the actual error messages you see in the log files.

I would like you to post the output of the Split DNS 'Verify...' commands here so we can check that they are actually working correctly.

3. host foxtrot

foxtrot.company.com has address 192.168.1.5

[phoenix]

The additional information (run on the zimbra server) I also wanted from the Split DNS article is this:

cat /etc/resolv.conf
cat /etc/hosts
host `hostname`

NOTE: The host `hostname' command should be typed exactly as you see it using backticks not single quotes and don't change the word "hostname" to anything else.

/etc/resolv.conf

manager@foxtrot:~$ cat /etc/resolv.conf 
search company.com
nameserver 192.168.1.2

/etc/hosts

manager@foxtrot:~$ cat /etc/hosts
127.0.0.1	localhost
192.168.1.5	 foxtrot.company.com	foxtrot

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

host `hostname`

manager@foxtrot:~$ host `hostname`
foxtrot.company.com has address 192.168.1.5

[phoenix]

Your hosts file is incorrect, the following line:

127.0.0.1	localhost

should look like this:

127.0.0.1	localhost.localdomain localhost

Fix that and restart Zimbra nad see what happens then post again.

[plastilin]

Already change, reboot... Nothing changes - mail in quie with second thread error...

foxtrot:/home/manager# cat /etc/hosts
127.0.0.1	localhost.localdomain	localhost
192.168.1.5	foxtrot.company.com	foxtrot

[plastilin]

Ithink the error is that provider check zimbra server for user zimbra@foxtrot.company.com, but zimbra server don`t have this user and relay don`t send e-mail...
