Don't send email local after install zimbra with DNS external

[snake_eyes]

Sorry for didn't answer to your questions.

1. I'm facing a problem with the mail delivery to hotmail and gmail as they send and NDR as below:

Remote-MTA: dns; gmail-smtp-in.l.google.com Diagnostic-Code: smtp; 550-5.7.1 [123.45.67.189] The IP you're using to send mail is not authorized to 550-5.7.1 send email directly to our servers. Please use the SMTP relay at your 550-5.7.1 service provider instead. Learn more at 550 5.7.1 'The IP you're using to send email is not authorized...' - Gmail Help s8si24828960eeo.43

Please note that it was working well without any problem.

Anyway in order to avoid such as this problems, I tried to use the relay host and I applied the following settings:

zmprov ms mail.domain.com zimbraMtaRelayHost mail.domain.com:25
echo mail.domain.com albabasw@domain.com:word456 > /opt/zimbra/conf/relay_password
postmap hash:/opt/zimbra/conf/relay_password
postmap -q mail.server.com /opt/zimbra/conf/relay_password
postconf -e smtp_sasl_password_maps=hash:/opt/zimbra/conf/relay_password
postconf -e smtp_sasl_auth_enable=yes
postconf -e smtp_cname_overrides_servername=no
postfix reload

Please note that there is A record if you read the DNS that I provided. Also the Cpanel is for me and I have root access too

Any help would be appreciated...

Not only that but your question/problem has nothing to do with this thread - start a new thread next time. You also didn't answer all of the questions I asked such as how long has this been happening and some idea about your ZCS installation such as ZCS version?

They've given you the reason for that error.

I looked at the DNS and you have no A record that points to the server IP mentioned in your hosts file.

I tried to change the IP in the hosts to be the public IP address of the server instead of the local IP address

After changes the zimbra wont work and gave LDAP faild to start and read from cache.

Please note that with the same current configuration, it can be able to send to gmail and hotmail from the whm "relay" server, but cant sent to the same domain, it gave loop back to it self, when I change the resolv.conf from 127.0.0.1 to 192.168.0.2 whch is the local DNS it can be send to the same domain but gave timed out to hotmail and gmail.
