First, i'm not only protecting my network, i'm also protecting your
domain from people who try to send email on your's domain behalf
to my users.

and you are missing one very important point, current smtp schema is by
itself insecure, there is no widely spread way to check that the sender
has relaly sent the message. This is a security problem that obviously
when solved will imply that the receiver host will try to check the
message auhtenticity by connecting to the sender's domain servers
(SPF, DKIM, callout, whatever ...) Will you call this abuse ?? If
you want a secure and reliable email service you will need to spent
some of your resources when other's try to validate any aspect of
any email sent using your domain.
