Hi Alex,
so you would like to block all /24 net if any ip address within this
network is in your database?
Meseems you should use >>= operator in your sql query(which you didn't
provide - I'm guessing how it can looks like) and condition create as
below:
condition = ${if eq{${mask:$sender_host_address/24}{${lookup
pgsql{PG_Q_BLACKLIST}}}}

Marcin
