I will read the draft in the coming days. I am all in favor of
outsourcing complex policies (for example, I do not expect to see
an XML processor in the Postfix trusted code base).
In the case of SMTP server policy, that was relatively easy to
implement (reuse the code that implements access map support), but
there is nothing to reuse, yet, on the SMTP client side.
