Not only Outlook... :(
Your "mail polisy" now (at whole, as I think):
Get and deliver mail from anywhere to registered mail addresses.
Drop mail from spammer MX-es or networks (blacklist).
Send mail from registered mail addresses (??) to anywhere.
Drop other mail.
To stop such spam, it must be
Get and deliver mail from smtp auth (Your) clients from any host to anywhere.
Get and deliver mail from well-known hosts without reverse FQDN (aol.com,
gmail.com, etc... - put it's IP addrs into whitelist) to registered addresses.
Drop mail from spammer MX-es (blacklist).
Get and deliver mail from hosts with *good* reverse FQDN to registered
addresses. "Good FQDN" is not auto names like 11-222-33-44.adsl.provider.net -
details in http://www.gabacho-net.jp/en/anti-spam/anti-spam-system.html
(maybe) Greylist other mail or protocol wait.
(best choise) Drop other mail.
Main idea is to drop direct mail sent from any host (without reverse FQDN or
with auto reverse FQDN) to Your registered mail addresses *directly* by Your MX.
