There are some issues in Zimbra 5.0 GA that you should know about.
Zimbra can install/upgrade and work under most circumstances, however, a small number of users are encountering some issues.
We wanted to post this thread to let you know about these, and help you work through any issue you have.
Issue:
Problem with Certificate can cause MTA Failure [ http://bugzilla.zimbra.com/show_bug.cgi?id=23253 ]
Symptom:
When MTA starts up, user will receive the following message in the /var/log/zimbra.log file:
Error:
postfix/trivial-rewrite[6172]: fatal: ldap:/opt/zimbra/conf/ldap-vad.cf(0,lock|fold_fix): table lookup problem postfix/trivial-rewrite[19377]: fatal: ldap:/opt/zimbra/conf/ldap-vad.cf(0,lock|fold_fix): table lookup problem postfix/trivial-rewrite[19378]: error: dict_ldap_connect: Unable to set STARTTLS: -11: Connect error
Then the MTA (postfix) will stop functioning resulting in mail delivery failure (via lmtp and smtp).
Common Cause:
CA chain can be appended in reverse creating invalid Certificate
Workaround:
