I just tested how Zimbra handles SPF by sending a mail from a domain with a hardfail SPF record. Zimbra assigns 0.001 spam points to it...

Isn't that kind of low? I know I can customize spamassassasin, but I was just wondering what the official SPF function of Zimbra is. Or will the score increase as soon as I start marking such messages as spam?

The wiki documentation seems outdated; for one, I don't think it's necessary to install separate software to get SPF working, seeing as how it already mentions SPF in the spam header.

Any thoughts are welcome.
