These are not main.cf parameter overrides. The access(5) FILTER action
does not override the transport_maps setting in any other service. It
does record transport:nexthop *value* in the queue_file that pre-empts
normal transport lookups, but this is very different from changing some
other service's setting the variable that defines the list of tables to
consult.
The queue file containts the message envelope and body, plus a small
amount of metadata that includes DSN attributes, content encoding domain,
... and sometimes a content_filter setting. There are NO main.cf parameter
settings in the queue file.
