Zimbra, DNS & Postfix \ MTA

[stillwell]

What in the World am I doing wrong here? I've been here for countless hours tinkering with these configurations. I can get the web interface for both admin and user to come up:

as user zimbra,

zmcontrol start

Everything starts, I send an email - It bounces back from Postfix (and does not reach the desired email account)

zmcontrol status

Then says that MTA is stopped as well as postfix.

... I have 'chkconfig postfix stop', made sure that it isn't running and MTA will say that it is running when I check the status. Then I send an email, it bounces back from postfix and I have to kill -9 Zimbra's version of postfix to get it going again.

Please respond ASAP-Hopefully there is a simple solution!

Kind of hard to say what the problem is, at least for me. You really need to look at the system and Zimbra logs (/var/log/messages, /var/log/maillog, and /opt/zimbra/mailbox.log) for more info. Here's a few things I see in your configuration files that could be causing issues:

1) You /etc/hosts files doesn't look right. I think you want to get rid of the "74.53.2xx.226 mydomain.com" line. Also, the "74.53.2xx.226 mydomain.com" should be "74.53.2xx.226 mail.mydomain.com mail".

2) You modified a chroot zone file, but you're working on the /etc/named.conf file. If you really are running in a chroot environment make sure you /etc/named.conf file is a symbolic link to the chroot area.

3) Not sure if this is due to some editing that you did to protect your actual environment, but you list the your zone file as mydomain.com.zone, yet your named.conf file refers to myhost.com.zone.

Also, you didn't post it, but make sure you /etc/resolv.conf file is correct. If you haven't already done so, I would recommend reading the Wiki and Forums for information on setting up DNS with Zimbra.

Hope this helps. Post back more detailed error information if you are still having problems.

[stillwell]

1. I got rid of the 74.53.2xx.226 mydomain.com
Also, the "74.53.2xx.226 mydomain.com" should be "74.53.2xx.226 mail.mydomain.com mail"

2. The named.conf is a sym link to chrooted

3. Have Pri and Secondary DNS servers in resolv.conf

For some reason my bash prompt says

[myusername@mail ~]$




I did the changes and now when I log into the web interface I cannot receive or send emails, where before I was able to retrieve them and when I sent them I got a postfix bounce.

Now when I try to send them I get this error:

msg - system failure: MessagingException
code - service.FAILURE
method - ZmCsfeCommand.prototype.invoke
detail - soap:Receiver


Who knows? :\

If you search the forum or wiki or read the Quick Start Guide you will see that your /etc/hosts format is incorrect and you'll see how to check your DNS. Do these commands:

host `hostname`  <-- backticks not single quotes
dig  yourdomain.com any
dig  yourdomain.com mx

Hello,

I now I have Zimbra setup on one domain, where I eventually would like to have it host separate email accounts on different domains on the same server. I can currently receive email, but when I send it I get the postfix "Subject:Undelivered Mail Returned to Sender" message.

I can access the user (obviously since I can receive email) and admin pages.
I'm close, please help!

What is my next step? It would be nice to have everything configured with at least two domains setup by this weekend.

Thank You,

Are DNS Lookups enabled? If not, then try enabling them.
