Proposals such as MTA Mark allow people to say which IP address should
be able to send email. While this is an interesting idea, I think
that is not a very good solution. If an organization wants to block
port 25 from IP addresses, it would be far better to block the port at
the boarder rather than publish information that other people have to
consume bandwidth checking and then rejecting the port 25 traffic.
Maybe I misunderstood something.
Checking the helo string if the mail from is the empty string _and_ the
email is a spam has no advantage?
