Probably not the most efficient, but possibly one of the simplest, ways of
doing this is as follows:

- create lists of local-parts, one per domain, e.g.
  /etc/exim4/domains/example.com
  /etc/exim4/domains/example.net
  e.g. each file would contain lines like "bob", not "[email protected]"

- in the router do something like "local_parts =
  lsearch;/etc/exim4/domamains/$domain"

- if you like you can also change the way that PrDomains is defined (
  dsearch;/etc/exim4/domains ) and thus do away with the /etc/exim4/PrDomains
  file (assuming nothing else is using it).

Test.  (above is untested, hopefully I'm not half-asleep and talking nonsense).
Make sure that valid users get routed correctly.  Make sure that /invalid/
users fail to route.  And make sure that acl_smtp_rcpt includes "require
verify = recipient".
