Obviusly spam isn't marked.

Hi,
I’ve got a server running virtualmin + webmin with a few e-mail accounts.
I recently began receiving obviusly spam emails, and i’m thinking that this could be stopped, if my spamassasin would do a spf checkup on the senders adress.
Is there any way that this could be done?

Howdy,

When looking at the email headers for that particular email, what is the x-spam-status email header set to? That will show which SpamAssassin rules were triggered.
