This post is about How to install free email server Kolab Groupware on CentOS7
Kolab uses IMAP as an underlying protocol for email, contact, and calendar entries. These entries are saved in IMAP folders in Kolab XML format, and the IMAP server controls storage and access rights. LDAP does configuration and maintenance of Kolab.
Kolab Clients and the Kolab server using well-established protocols and formats for their work (i.e., IMAP as mentioned above, vCard, iCal, XML, and LDAP). This allows the Kolab Format specification framework, or even portions of it, to be utilized as an open set of specifications for groupware clients and servers to communicate with each other.
