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.
