How did you know my environment? It is a nightmare actually. If any real and important mail is sent to those addresses then it is probably buried under all the spam, making those addresses pointless. That is why I suggested, rather than completely removing them, the possibility that the mailer could be configured not to allow external mail to system users and related aliases. I could probably dig around in the documentation and find a way to do that myself but I was curious if anybody had already done so and documented their solution. Regards, Daniel
