Thanks in advance for any thoughts concerning my issue below:
We have auto mail routing and replication setup between several other Domino servers sitting outside of our local network, each server having different domains (We are using R6). At ServerA, we use a SPAM filtering system (Postini) that sits outside of the server. All mail gets filtered through their portal first before it hits our mail server. However mail that gets relayed to us via one of our trusted servers comes through unfiltered. The problem is, Spammers can send to myaddress@ServerB.com (ServerB doesn't have Postini) and then ServerB automatically relays the message to my inbox on ServerA. I've played with the inbound relay controls, but have been unsuccessful with trying to force mail from ServerB to get routed through our Spam Filter. Any suggestions?
