Re: question about return code .255

[Patrick Domack <patrickdk@xxxxxxxxxxxxx>]

I am also using unbound.
I went through my logs for the last 6 months, and I have never seen  
this response code.

I found dnswl didn't help postscreen at all, and removed it from my  
postscreen config.

It does look like I don't do a lot of lookups to dnswl though, since  
most ip's have already made it onto my whitelist or blacklist due to  
previous reputation and do not need to be queried.
