Like so:
hostlist blacklist_hosts = ${lookup
mysql{servers=OTHER_MYSQL_SERVER/db/username/password;Q_BLACKLIST_HOSTS}}
OTHER_MYSQL_SERVER can be defined previously for example:
OTHER_MYSQL_SERVER = 10.0.0.10/database/username/password
so you can simply use:
hostlist blacklist_hosts = ${lookup
mysql{servers=OTHER_MYSQL_SERVER;Q_BLACKLIST_HOSTS}}
hope that answers your question.
