OK.

Not sure if this will help either, but this can be done on local_part, or for
that matter, 'Subject:' or any of several other headers as well - even on
arrival port and/or auth method and protocol, and still (largely) in acl's.

We use 'warn' verbs to set a flag in an acl_c and/or acl_m variable to guide the
flow through ELSE bypass (with 'endpass') subsequent acl traversal, and/or add a
header of our own, then set router/transports to trigger on the *special header*.

Said 'ad hoc' header is ordinarily removed as part of the delivery to keep the
environment a bit cleaner.

Using the acl's to generate the header makes it a bit more straightforward to
design the router/transport sets, as their conditionals can be simpler and more
certain.

Most concrete examples used here (SQL driven) are too complex to be helpful, but
rest assured that you CAN do what you want.

HTH,
