Hi,
I've expirianced strange issue. The same email sent to different people ins't check by the same spam checks thus it gets different 'Hit' number. In result some spam is blocked and some goes through. Even though the content of the message is the same. Please find a part of my maillog below. We can see not every message was chaced against "RCVD_IN_BL_SPAMCOP_NET=1.347,RCVD_IN_RP_RNBL=1.31" How can it happen?
