Perfectly standard de-tainting method, to get the filename for the
lsearch.

senders = lsearch;${lookup {$local_part} dsearch,ret=full {/usr/lists} {$value}fail}


You could break that up, to make the sequence more clear:

local_parts = dsearch,ret=full;/usr/lists
senders = lsearch;$local_part_data

(although that still relies on the documented sequence of evaluation of
router preconditions; which is not the sequence as written in the
configuration text)
