anti spam policy - hub transport server or edge transport server
Posted on 2009-04-17
i have an environment where the edge transport server is a Linux Box with Sendmail installed on it ... Currently, there is no anti spam thing on that box (as I havent read details on how to do that in Linux) ... Next, I have a hub transport server which is Exchange 2007 that delivers all teh emails to my domain's email addresses ... I dont have an anti spam configured there as well ...
I would like to general recommendations on where should anti spam policy be defined ? Edge transport server or Hub transport server ? from the concept, it makes more sense if we define it on Edge transport (i.e. the Linux one) .. But is there any downside if i dont define any anti spam policy there on Linux Box and simply define it on my Hub transport server which is Exchange 2007 ? Whats the drawback (if any) in doing so ?
