I already use ORF to reject at the envelope using LDAP lookups and
really have no need for any other intermediary. It's no-brainer if you
use IMail's NT integration on an AD DC. All you need to do is add the
Exchange schema extensions to the AD domain, since ORF is expecting
the extended schema--you don't have to install or purchase Exchange
itself. You can run the ORF queries against any server in the domain
(which doesn't have to be the same as your primary domain), meaning
that you can scale out from hitting the mailbox server directly to
hitting dedicated AD DCs that only service such MX lookups.
Building anything designed to interact with IMail's own ILDAP daemon
is a very bad move, as the service is barely functional, compliant, or
stable. AD's LDAP services, on the other hand, are mature and
resilient.
The other options that involve local text files would certainly work,
but performance under load could not exceed that of indexed LDAP
lookups.
