How and what to register router for Exim?

Question

Exim

There is a tracker of letters that come to the server in the format, for example
, [email protected]

The task is not to refuse that the address or domain does not exist.
Put all letters in 1 folder.

Tell me how to register a router?
I tried adding this router to the end but it doesn't work:

# catchall router

local_catchall:
debug_print = "R: catchall for [email protected]$domain"
driver = redirect
domains = +local_domains
allow_fail
allow_defer
data = catchall

Answer 1

I could be wrong, but it seems that this router needs to be placed before local delivery
