Ah, yes. I understand. Thanks. My understanding would be that it's not a
good idea to use the PBL further up the list of hops from the last
external source, for the very reason you may well pick up the initial
client to sending relay connection - which would most likely be in the
PBL {dynamic DSL customer connecting into to his/her ISP mail server}.
