      Had this error after installing a new commercial certificate. The error seems valid as my server hostname and certificate name do not match, but it is my understanding this name mismatch is allowed and should still work.

      To resolve this I just ran these two commands as Zimbra user.
      zmlocalconfig -e ldap_starttls_required=false
      zmlocalconfig -e ldap_starttls_supported=0

      I am slightly concerned as to the security implications of disabling these settings. I am still on ldap not ldaps and this is on CentOS 7.

    I have followed your article on “How to Install Open Source Zimbra Mail Server (ZCS 8.8.10) on CentOS 7”, but always fails and hung on the configuration process, i.e.:

    Initializing store sql database…………..

    This process hung infinitely.

    Do you have any suggestion how to solve it according to your experience.

    Look forward to hearing from you soon.

    Best regards,

      It seems like MX record is not configured for your test domain, also make sure your system points to correct DNS server where your domain records are configured.
