Hi Rob and list,

Speaking as a small user of SORBS via SpamAssassin 4.0, I assume the
correct response to disable use of SORBS is to place the following in my
local.cf file:

     dns_query_restriction deny sorbs.net

Is that correct and is there any additional portions of local.cf I need
to configure so that I am no longer consulting SORBS ?

Thanks,
