Your pattern is "invalid" for nwildlsearch. Indeed, it is read as
"arbitrary sequence of symbols followed by string '*.domain_to_block.com'",
where "*" is treated literally. Look here:
# echo '*@*.domain_to_block.com' > /tmp/blacklist_domains
# exim4 -be
'${lookup{[email protected]_to_block.com}nwildlsearch,ret=key{/tmp/blacklist_domains}{$value}{NONE}}'
NONE
# exim4 -be
'${lookup{jon@*.domain_to_block.com}nwildlsearch,ret=key{/tmp/blacklist_domains}{$value}{NONE}}'
jon@*.domain_to_block.com
Use regular expressions, they are recognized as strings started with
caret (^). Read description of nwildlsearch for details.
