Is it possible to write a lookup for an [email protected] and

You're making life difficult with that ".txt" element,
Assuming you want this in a router,
something along the lines of
address_data = ${lookup {${local_part}.txt} \
dsearch,ret=key,filter=file \
{GIVEN_DIRECTORY} \
{${sg {$value}{\.txt\$}{}}} \
fail \
}
with the verified value arriving in $address_data ?
Note that the address_data option is evaluated after the rest of the
router preconditions, so you can't use it's result in the local_part
option. So that "fail" is needed, to do the work of the local_part
option test.
