*nod* In the OP's configuration I'm pretty sure you can't really do anything other than systemwide settings; there's no mediating glue layer to allow for reprocessing or splitting multi-recipient messages to allow MTA-level per-user behaviours. Switching to calling SA by way of an intermediate content filtering framework like Amavis or MIMEDefang would give you a lot more flexibility, but I don't know how well you could support SA's own per-user preferences system even then. -kgd
