We have been using a router as suggested by the manual for
closed lists restricting posts to some senders but now they
are rejected with
Tainted filename for search
lists_post:
driver = redirect
domains = lists.example
senders = ${if exists {/usr/lists/$local_part}\
{lsearch;/usr/lists/$local_part}{*}}
errors_to = ${quote_local_part:$local_part-request}@lists.example
no_more
But I cant get the senders to be detainted using a lookup
in the file of allowed senders. An example will be appriciated.
Something like
${lookup{$sender_data}lsearch{/usr/lists/$local_part}}
