I restructured the postconf code 12 months ago, to add support for "unknown parameter" warnings, service-dependent parameter names (foo_destination_concurrency_limit etc.), and master.cf. Thanks to this, it is no longer a problem to add support for parameter expansion. I'll have a fully-working version by the end of the day. Wietse
