do you mean you have not taken the time to lookup your-exim-source-
dir/doc/spec.txt? Because, if you had, you would have found that:

is what local_part_suffix is about.

you are asking if something is possible with exim4? The question
should be the other way 'round: find something that is not possible
with exim...

too difficult with Exim4? Again: take your time to read the spec.txt
(or its html version, on the site).

sorry, but I did not understand your current understanding.

Anyway, in a router:

local_part_suffix = -*
local_part_suffix_optional

will do what you want for determining what a local_part is, then you
can do what lookup you find more suitable to determine if a
local_part is valid.
