I have some questions about RBL's in combination with Zimbra.
I found on the wiki some examples to enable RBL checks for Zimbra.
But what is the weight of those checks than ? I couldn't find that really, because I don't want that messages are going to be rejected only on the RBL check base, but the combination of the RBL's and other spam checks.
So is it possible to use RBL's but than that it is not the deciding factor if a message 'is' SPAM or not but only to get the score higher, and if the other checks also says it is SPAM than it may removed off course
