Perfectly standard de-tainting method, to get the filename for the
lsearch.
senders = lsearch;${lookup {$local_part} dsearch,ret=full {/usr/lists}
{$value}fail}
Thank you.
But the router has both open and closed lists where the closed have a
file $local_part.allowed
Unsuccessfully trying
senders = ${if exists {/usr/lists/$local_part.allowed}\
{lsearch;${lookup {$local_part.allowed} dsearch,ret=full {/usr/lists}
{$value}fail}}
If I understand correctly
"exists" does not untaint a filename.
