[Exim] external lookups

Lo everyone,

It is possible to have regex lookups in things such as text files?

I have for example,

sender_reject_recipients = partial-lsearch;/some/file

where /some/file can have domain.com *.domain.com etc...

Now, I want to have something like *.domain[1-0].com for example - hence, a
regex lookup.
