[syslog-ng] in-list for message

Can syslog-ng parse the message field for a partial match using the in-list function? For instance, I am querying DNS logs and want to filter out common domains (i.e. Microsoft.com, Redhat.com) In my list file I just have the domains, one per line and in my config file, if have the following: filter f_dns_noise_oklist { in-list("/etc/syslog-ng/lists.d/dns_noise.list", value("MESSAGE")); }; but it doesn’t seem to be working.
