I think you still don't clearly have the distinction made about who is
blocking what.....

No DNS "black-list" blocks anything whatsoever at all.  _YOU_ do the
blocking _IFF_ you use the lists in that way.

That's simply not true at all, especially not in this day and age when
even the most lame of MUAs available to the average person is capable of
doing SMTP AUTH.  Nobody is ever forced to use their connectivity
provider as their e-mail provider.  If your friends are under this
impression then you should try to inform them of the many alternatives
they have.  Perhaps you yourself could offer them secure and safe e-mail
services!  :-)

Of course sometimes this means running POP (or IMAP) and SMTP on
non-standard ports, since some ISPs do restrict their users rather
drastically, but that shouldn't be too much of a problem to deal with.

Don't use their services then.  Don't let your friends use them either.

When the DNS list at was truly freely available it
was very effective at stopping directly delivered spam.  There are some
similar lists elsewhere, but they are not quite so complete.....

I use the DNS list at  It is very effective. 

In combination with the other black-lists I use I only get about one
directly addressed and delivered spam per day now.
