You should probably use a router with local_parts and domains settings
and verify_only, fail_verify set, to force verification for local parts
you do *not* recognize. VERY roughly (off the top of my head, unchecked):
xxx:
driver = domainlist
verify_only
fail_verify
domains = the.domain
local_parts = !lsearch;/list/of/local/parts
route_list = *
In Exim 4 there is a "call forward" feature which will let you to
dynamic checking by making an SMTP call to the host you are relaying to.
Also, with the merging of directors and routers, the kind of approach
suggested above becomes much simpler.
