Hi all
Is there anyway of stopping the from "j...@foo.com"
<mailto:from...@foo.com> to "j...@foo.com" spam attacks?

If you're not using zen.spamhaus.org already, you should
start. If your site is too large to qualify for their free
use, the paid feed is well worth it.
You can use a policy server that rejects mail when the sender
and recipient are the same. It's reported that postfwd can do
this, probably others too.

Some people reject their own domain from outside,
unauthenticated clients, but this will certainly reject some
amount of legit mail.
