Here you go :

#
# First weed out the blacklisted spammers
#
if "${lookup {${local_part:$header_From:}@${domain:$header_From:}} lsearch {$home/util/mailfilter/spam-from} {Spam} }" is "Spam" then
    seen finish
endif
############



If you read the manual it says that 'lsearch' is not just a flat
list (it is a mapping). However, if you ignore the result of the
lookup and are only interested in success/failure, then it is
functionally the same thing. However you can't include certain
characters in the blacklist, such as ":", because the lsearch will
think the key part has ended and the value part is beginning.
