So that's not all DSL users, but only thise who have a dynamic address,
so why use all xDSL ? : and do not limit yourself to the DSL market in
your country, I know companies on DSL line, with fixed address and
reverse. You speak of xDSL, what about SDSL, which is a company only
solution, and I known of many SDSL providers which do not provide a smtp
server...

Hay I've just a way to cut *all* spam : just cut email. You will cut all
spam.
Or just refuse email originating on a windows PC.


The efficiency of antispam measures is not only the number of spam it
blocks, but its also the number of non spam it does not blocks. Your
"solutions" are awfully bad in this regard.

I did tun email for the company I worked for before, and no problem with
this provided I used other filtering method. The other companies for
which I worked also accepted email from my server, including the one I
work for today. And I can testify their antispam is very efficient :
almost none received and I've yet to see one false positive
