The standard SA ruleset includes an extensive list of domains in uridnsbl_skip_domain. 
The idea is to skip RBL lookups for domains that are unlikely to be on a blocklist. 
However it also prevents lookups on "welcome" lists such as dkimwl.org.

I'm thinking of implementing a new tflag `noskip` that bypasses the skip list 
for askdns rules. Or we could repurpose the `nice` flag so that nice rules 
automatically skip the skip list.

Alternative 1:
Remove legit domains from uridnsbl_skip_domain, and just use it for domains 
like example.com that would never be on any list. This would obviously increase 
DNS queries.

Alternative 2:
Make two separate lists such as `uridnsbl_skip_good_domain` & 
`uridnsbl_skip_bad_domain` so we can skip looking up good domains on bad lists and 
bad domains on good lists. Domains such as example.com could be on both lists.

Any thoughts?

I think we should use a noskip `tflag`, creating two lists would be complex to 
maintain since we need backwards compatibility for older SA versions.
