Hi everyone,

Fyi, I've installed the zimbra network edition version 8.0 with mail, ldap, mta, snmp services on my CentOS 6.3 (64-bit) vm server and everything works fine.
And I've also installed another zimbra server which serves as a MTA (with ldap(replica), mta, snmp services), but I'm stucked halfway cos the services failed to start..errors as shown below:-

Host mta.zimbramail.com
Starting ldap...Done.
Unable to determine enabled services from ldap.
Enabled services read from cache. Service list may be inaccurate.
Starting zmconfigd...Done.
Starting antispam...Done.
Starting antivirus...Done.
Starting snmp...Done.
Starting mta...Failed.
Starting saslauthd...saslauthd[15679] :set_auth_mech : failed to initialize mechanism zimbra
failed.

opendkim: /opt/zimbra/conf/opendkim.conf: configuration error at line 0: error reading configuration file
Failed to start opendkim: 0
zmopendkimctl failed to start
Starting stats...Done.

Is there anyone out there that could help me solve these errors? your help/idea is very much appreciated. Thank you!
