"dkim=fail reason="fail (message has been altered)"" but email is not rejected

Post by copowpow »

Hi guys, on zimbra colab 8.8.15_GA_4372

I am getting some sender address spoofed emails passing thru to inboxes and im not real sure how to make it so the altered emails dont hit an inbox.

heres whats in the email source:

"
Authentication-Results: mail.derp.com (amavisd-new);
dkim=fail (2048-bit key) reason="fail (message has been altered)"
header.d=aol.com
"
Im guessing to get this to work correctly, there is a setting to change in a config file somewhere, any advice as to what config file that may be?

Thanks!
