Martin Konold: Add two new attributes 'kolabAllowSMTPRecipient' and 'kolabPolicyDaemon'. The former is added to kolabInetOrgPerson while the later is added to the kolab objectclass. kolabAllowSMTPRecipient describes the allowed or disallowed smtp addresses for recipients. If this attribute is not set for a user no kolab recipient policy does apply.

entry examples:
.tld - allow mail to every recipient for this tld
domain.tld - allow mail to everyone in domain.tld
.domain.tld - allow mail to everyone in domain.tld and its subdomains
user@domain.tld - allow mail to explicit user@domain.tld
user@ - allow mail to this user but any domain
-.tld - disallow mail to every recipient for this tld
-domain.tld - disallow mail to everyone in domain.tld
-.domain.tld - disallow mail to everyone in domain.tld and its subdomains
-user@domain.tld - disallow mail to explicit user@domain.tld
-user@ - disallow mail to this user but any domain
