     Not true.  One doesn't have to make it a blanket reject.

     Not true.  Again, one doesn't need to make it a blanket reject.

     Not true.  There are methods to collect such data from the users.

     While this is true the highest I've seen is 5.6.  I reject at 8.  If
you're worried, set the reject threshold higher and pass it on tagged.  I
doubt you'd ever see a false positive at 10 or so (esp. with Bayesian turned
on) and even if you did it would be so extremely rare that it is worth the
loss (thousandths of a percent if not millionths of a percent).

     Which is far preferred to the movement towards C-R and other systems
which severely break how mail is supposed to work.

     Not true.  Whitelists exist.  Give the users the ability to add their
name to it.

     It has little to do with exim configurations and a whole lot to do with
Spamassassin configuration.


> Desktop tools return the control to the users.


     Most desktop users don't know what to do with that control.  It is far
easier to reject the blatent cases, tag the marginal and tell them to filter
on a single header than it is to try to educate the masses on proper email
management.  If given the choice of setting up Spamassassin (or spamprobe, or
spambayes) versus a C-R style system most will set up the C-R system because
it is far easier for them to set-up and maintain.


     Sensible defaults with the ability for the end user to opt-out is not
censorship; it is being responsible and realistic about the capabilities of
the average user.
