SpamAssassin already has 2,133 domains listed via freemail_domain, so you
shouldn't need to add that part for any domain.  If you do, you should file
a bug to get it added.

The rule that goes with this is FREEMAIL_FROM, which has a default score of
0.001 (basically nothing), because it hits 21.6% of non-spam (11.4%
of spam).

But if you want it to actually do anything, you'd need to increase the
score via something like:


But these scores are chosen by some pretty extensive real world data

It looks like the way to just penalize a single domain would be:

blacklist_from *

By default it has a score of 100, which would usually block everything.  

I was actually doing something with a similar effect, to hotmail for a 
while.  I recently noticed yahoo is much worse, I think this graph deserves 
its own post:

I had always assumed the spammers just registered the accounts directly.
Why do you think they were stolen, by viruses or otherwise?
