I am playing with ZIMBRA 7.0.0_GA_3077.UBUNTU10_64 UBUNTU10_64 FOSS edition and Mailarchiva.
If I use the milter server setting on the MTA page of the Server Icon in the webadmin, and add the IP address of my Mailarchiva server, Zimbra sends mails correctly to Mailarchiva, and to everywhere else they are supposed to go.
So, no problems there.
Here is my question: Is this a valid use of that feature? Does doing this mean that I am breaking something else in zimbra (i.e. bypassing some other anti-spam feature?)
What exactly is this feature in Zimbra supposed to be and what is it used for?
