We have installed GroupShield Domino 5.0a with Hotfix4 on a new Lotus Notes Server 5.0.8 which just routes and scans our messages. Our Mail that flows after our GS5.0a through another viruschecking Notes Server is doubled on this (second) Virus Checker and therefore delivered twice to the recipient. This happens if the second VirusChecker is a GS4.5 or with TrendMicro Scanmail 2.5. It seems to be independant on the product / version of the second VirusChecker. Does someone knows anything about this problem?
