No. The new extended caching still applies only within ONE Exim process.
The receiving process and the delivery processes are not the same
process. The only way to get inter-process caching is for somebody to
implement a new daemon that keeps a local cache of database queries (for
Exim and any other local applications). This has been talked about
before, but it is not a simple thing to write.
