I have been asked to come up with an LDAP setup and filter for our mail
servers which they will use to determine an emails policy for anti-spam
etc. I have been told it needs to check LDAP for a specific user, but
if there is no user and policy defined then to use the settings that
have been configured for the domain. I have the simplified objects:
---- User object -----
dn: uid=user@mydomain.com
mailpolicy: PolicyA
Is it possible to have a filter that will match the user object if it
exists, and fallback to the domain object if not? I don't think this is
possible myself as surely the filter is being applied to a single object
at a time and not checking for the existance of 1 object before matching
another? I initially thought:
