As disusssed here on several occasions some blacklists assume that _all_
DSL addresses are dynamic (and hence are spammers). This ignores the
reality of what many ISPs are selling to their customers, especially
those that refuse to setup sensible reverse DNS pointers.

The only thing to do is not use sorbs. There is nothing else _you_ can
do (apart from whitelist the sender as you sugest).
