LDAP mails are dropped

[Mudasar]

Hi,

We have configured LDAP on zimbra, it is working fine. I have disable all checks of protocol and DNS on Primary server and enable all these checks on secondary server. I have verified these checks are not replicated that is fine for me. But on my primary mail server mails are dropped due with these checks

--------------------------------------------------
Apr 12 01:14:39 zm1 postfix/smtpd[13786]: NOQUEUE: reject: RCPT from unknown[xx.xx.xx.xx]: 450 4.7.1 Client host rejected: cannot find your hostname, [xx.xx.xx.xx]; from=<655NAD@hotmail.com> to=<mgrkhi@mydomain.com> proto=ESMTP helo=<[xx.xx.xx.xx]>

How can i avoid this?

DNS issues so please post

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes

Also, what does it mean

We have configured LDAP on zimbra

are you replicating the LDAP yourself ?

Hi,

LDAP replication is automatic.

I think there is no issue with my DNS record, the log messages that i have post were belong 2nd party. and these messages comes if i enable the "Protocol and DNS" check for MTA.
And my requirement is that i need to enable these checks on secondary but not on primary. But when i disable it on primary and enlable on secondary it gives me errors and my primary server drop mails. I hope it will clear my requirements .
