* == Changes ==
* Non-Delivery Reports now originate from \"Mail Delivery System\" (like postfix) instead of yourself [KC-309]
* Support for building with a no-SSLv2 OpenSSL 1.1. [KC-230] If you run such a setup, be aware that a config setting like \"ssl_protocol = !SSLv2\" in one or more of kopano-{server,gateway,ical}.cfg can inhibit the process from starting.
* Cleanup of the example LDAP configuration files. [KC-229] /usr/share/doc/kopano/example-configs/ now has just a ldap.cfg, and no more ldap{,ms}.{active-directory,ldap}.cfg.
* The example LDAP config file now has a different proposed value for ldap_object_search_filter for OpenLDAP. [KC-218]
* spooler: messages with reminder will be sent with a TNEF copy [KC-152]
* admin: group features will no longer be shown [KC-239]
