NEEDED blacklist wildcard to block not only the domain but also subdomains.
The host that I just moved from had a wildcards (*) available in their
blacklist, we NEED it here. As posted and requested by others from
years past. The spammers only change the subdomain name to bypass the
blacklist, then we have to add that one to the blacklist. PLEASE add
this, save us all a lot of time!!!
