setuid=pdns-recursor
setgid=pdns-recursor
local-address=127.0.0.1, 10.0.0.70
local-port=53
additional-processing=on

Can confirm, this option (and its v6 counterpart) don't actually do anything right now (since 21f0f88). Will discuss.

As this has been "broken" since before 3.5, and nobody has reported actual problems resulting from it, we have decided to delete the dead code. A feature request ticket (with motivation) would be considered after 3.6.0
