This is a collection of LDAP schemas that could be used in a virtual mail environment consisting of Postfix, Dovecot, SASL and Roundcube.
postfix-book.schema was originally available from http://www.postfix-buch.com/download/postfix-book.schema.gz but is no longer around. Two new attributes have since been added to further enhance the schema without the need of loading multiple email specific schemas. These attributes include:
- mailSieveRuleSource
- mailForwardingAddress
Both postfix and dovecot benefit from using postfix-book.schema as their primary schema source.
