I received two separate spams advertising "uztiuqhcsgdnhsx.kennevur.com" and "678.com.plaweresoft.com" as the domains.
multi.surbl.org lists the domains as blacklisted:
host kennevur.com.multi.surbl.org
kennevur.com.multi.surbl.org has address 127.0.0.86
host plaweresoft.com.multi.surbl.org
plaweresoft.com.multi.surbl.org has address 127.0.0.118
but not the subdomains:
host uztiuqhcsgdnhsx.kennevur.com.multi.surbl.org
Host uztiuqhcsgdnhsx.kennevur.com.multi.surbl.org not found: 3(NXDOMAIN)
host 678.com.plaweresoft.com.multi.surbl.org
Host 678.com.plaweresoft.com.multi.surbl.org not found: 3(NXDOMAIN)
Why? Wouldn't it be easy/sensible to wildcard the blacklist to include these?
