zmhostname - outgoing mail problems

[Mo_Hong]

Hi Community,
We been facing an ackward problem with one of our servers. We have configured the DNS following all the guidelines on the forums and wiki, and it does resolve internally and externally, even the PTRs. The only thing that we have found different on the config is that we have on DNS:

mail.domain.com as MX, A and NS records

and

domain.com as zmhostname

In the zmhostname the hostname does no appear, and we have the problem that outgoing mail to some domains (hotmail, gmail, etc) are being held on the active queue or deffered, we looked on the zimbra.log and to the domains that is not delivering it gives the following error:

lost connection with hotmail.com[65.55.72.183] while receiving the initial server greeting

Is it possible that this issue might be blocking delivery?. Also, we have DNS lookup unchecked, because if we check it it starts to deliver ok to all outside domains but gives the following error when we deliver to the local domain:

<user@domain.com>: Host or domain name not found. Name service error for name=domain.com type=A: Host found but no data record of requested type

In advance, thanks for all the help you might give us. Please feel free to ask for the configuration files if they are needed (in case you think the problem goes beyond the issue stated before).

Regards,
Ed

According to the information you've posted it would appear your DNS or your hostname is not correct. Go to the 'Verify...' section of the Split DNS article and post the output of all the commands in that section.

Bill,
Thanks for your answer, I'll be posting as soon as I get tothe office. For what you tell me then, zmhostneme is wrong and should be in the form hostname.domain.com right?

Thanks,

Yes, that's correct but do check the details in the wiki article.

I've already seen a couple of errors, but I'll wait on your comments on this. By the way,

zmhostname
[zimbra@correo ~]$ zmhostname
domain.com

Your hosts file is incorrect, it should only contain the entries (two lines) mentioned in the wiki article.

[Mo_Hong]

Ok, changed the /etc/hosts file. Now we have the following erro when tryin to restar Zimbra services:

[zimbra@correo ~]$ zmcontrol start
Host fuller-ve.com
Starting ldap...Done.
Failed.
Failed to start slapd. Attempting debug start to determine error.
daemon: getaddrinfo() failed: Name or service not known

[Mo_Hong]

Changed back the /etc/hosts file to the following:

/etc/hosts
127.0.0.1 localhost localhost.localdomain
10.10.2.252 domain.com correo

and I could start again the Zimbra services.

[Mo_Hong]

Can I proceed to change the zmhostname and after proceed to change the hosts file??

[phoenix]

Changed back the /etc/hosts file to the following:

/etc/hosts
127.0.0.1 localhost localhost.localdomain
10.10.2.252 domain.com correo

and I could start again the Zimbra services.

That format is not correct, it should look like this:

/etc/hosts
127.0.0.1 localhost localhost.localdomain
10.10.2.252 correo.domain.com correo

Then: ZmSetServerName - Zimbra :: Wiki - make sure you take a backup before doing this.
