        Actually there can be false positive.  ISP's
        who put address blocks into "dialup" blocks
        which have the qualification that the ISP is
        also supposed to only do it if they *don't*
        allow email from the block but the ISP's
        policy explicitly allows email to be sent.

        They have a default port 25 filter that will
        be turned off on request. i.e. they allow
        direct out going email on request.

        The said ISP *thinks* they are doing the
        right thing by listing the block when in
        reality they are lying by listing the block.
