$h_From: contains the full header-line,
e.g.: "From: support blabla <exim-ml@???>"

${address:$h_From:} contains the extracted e-mail address
e.g.: "exim-ml@???"

if you want to filter out the word "support" from the variable $h_From:,
then you should not use the address extractor "${address:$h_From:}"

Write your config stanza as:

deny message = $acl_m1
set acl_m1 = ${lookup {$h_From:} nwildlsearch{/tmp/blacklist} }
condition = ${if eq {$acl_m1} {} {no} {yes} }

this should be ok
