(Hi, I am new here. Sorry if I have posted in wrong forum.)

Here goes my problem,

While sending an email I get this error,

Code:

I have performed all above steps but I still get the same error.

Code:

method: [unknown] msg: try again: Unable to connect to the MTA code: mail.TRY_AGAIN detail: soap:Receiver trace: com.zimbra.cs.mailbox.MailServiceException: try again: Unable to connect to the MTA ExceptionId:btpool0-7://mail.mycompany.com/service/soap/SendMsgRequest:1342128643811:e2cce8919c6b95df Code:mail.TRY_AGAIN at com.zimbra.cs.mailbox.MailServiceException.TRY_AGAIN(MailServiceException.java:479) at com.zimbra.cs.mailbox.MailSender.sendMimeMessage(MailSender.java:628) at ... more stacktrace...

OK guys I have resolved one issue, now MTA is running. The problem was sendmail service of OS was also listening to 25 and I stopped it.

But still I am not done yet, now when I send an email from web interface, it shows me message sent. But the recipient does not receive the email. I confirmed this by sending email to myself aswell to my gmail address.

Now, I went to documentation, Incoming Mail Problems - Zimbra :: Wiki,

It suggests to run this command,

Code:

host -t mx domain

I found the domain using, zmhostname command.
When I run host -t mx mail.mycompany.com it gives me,

Code:

Host mail.mycompany.com not found: 5(REFUSED)

Can somebody tell me what's wrong? Thank you

Yuves,

Thank you for your reply. Actually, I already replied in this thread that the problem was CentOS' sendmail service was listening to port 25 and after disabling that service I got passed that stage. (But, after posting that message I got the message that your post is sent for admin approval. so it does not appear here).

Anyways, now when I do zmcontrol status all services are running fine. I go to zimbra web interface, I send email and I get message, "message sent". but recipient does not receive it. I confirmed that by sending email to myself and to my gmail address.

I went to Zimbra wiki for incoming mail problem. I ran following commands, (though I do not fully understand them)

Code:

[zimbra@mail root]$ zmhostname mail.mycompany.com [zimbra@mail root]$ host -t mx mail.mymycompany.com Host mail.mymycompany.com not found: 5(REFUSED) [zimbra@mail root]$ zmlocalconfig -e postfix_lmtp_host_lookup=native [zimbra@mail root]$ zmmtactl restart Rewriting configuration files...done. postfix/postfix-script: refreshing the Postfix mail system Stopping saslauthd...done. Starting saslauthd...done.

This is what zimbra.log gives just after sending an email.

Code:

[zimbra@mail root]$ tail -f /var/log/zimbra.log Jul 12 22:20:26 mail postfix/cleanup[4529]: C6F28EB8867: message-id=<10edf0e7-538b-462f-a8b7-25905da5032b@mail.mycompany.com> Jul 12 22:20:26 mail postfix/error[6005]: A4AD0EB8866: to=<archive@mycompany.com>, relay=none, delay=0.28, delays=0.13/0/0/0.14, dsn=4 .4.3, status=deferred (delivery temporarily suspended: Host or domain name not found.

I think it has something to do with domain name.

Thank you again.

You're right, it is a DNS issue. First, your server 'mail.mycompany.com' is not pointing to an A record, as shown by this error:

You also have to setup the MX for mycompany.com to point to mail.mycompany.com.

The following line is also leading me to believe that the DNS on your server is not setup. Check the entries in '/etc/resolv.conf'
