How must be the entries on the Blacklist to block the whole Domain and Subdomains like xyz.domainname.com?
www.domainname.com or domainname.com ?
bassically putting xyz.domain.com will just block xyz.domain.com.
putting domain.com on the blacklist will block domain.com (evidently) and ALL it subdomains (including www.domain.com and xyz.domain.com)

Arrrgghhhh ... domain.com is not working ...
Wildcard support to block all of domain.com and *.domain.com is an as of yet to be implemented feature request. Be sure to vote for it in the feature request section: Wildcard support for domain black/white listing
Right now all you can do is customize your installation manually to block all of a domain, check out this post:

(also be sure to service dnsmasq restart / systemctl restart dnsmasq afterward your manual config modifications)
