 can't add X-Spam-Flag
It looks like some piece of Zimbra's mail delivery chain (postfix, amavis, spamassassin) removes the X-Spam-Flag header that my Brightmail anti-spam appliance adds. This, I think, is the header that Spamassassin uses to identify spam too.
I'd like to combine the spam-fighting abilities of my Brightmail appliance, and Zimbra's Spamassassin. But if SA removes the header that Brightmail adds, this doesn't seem to be possible.
Any suggestions? |
