I would guess that many (most?) ISP's use DNSBLs in the access db, so
you'll be rejected even before SpamAssassin can get its hands on the
message.

And if your ISP gets on a DNSBL, then the 99% of its customers who
use LookOut! instead of Emacs-GNUs will complain pretty quickly. :-)

On another topic:

I had an interesting experience trying to send my earlier message to
the SA-talk list.  I've configured my mail server to reject mail from
"<>" to "postmaster at roaringpenguin.com".  The theory here is that I
never send mail as postmaster, so I should never get any bounces to
that address.  Turns out Sourceforge's mail server does a check for a
postmaster@ account using "<>" as the sender address, and it was
bouncing my mail (because it looked like the postmaster@ account
didn't exist.)

To get around this stupid behaviour, I now defer the rejection to the end
of the DATA statement, keeping Sourceforge's lame checker happy, while
keeping bounces from forged spam off my system. :-)
