That will only work if you replace $sender_host_address with
${mask:$sender_host_address/24} in the lookup. But the lookup will not
then find the other entries. What you need is a double lookup. Something
like this:
smtp_accept_max_per_host = \
${lookup{$sender_host_address}lsearch{/path/to/file}\
{$value}\
{\
${lookup{${mask:$sender_host_address/24}lsearch*{/path/to/file}}\
}}
Note that the first one does *not* have the * on the search type. If you
have blocks of different sizes (/24, /26, etc) you will have to
configure it to do a separate lookup for each size.
