As has been told to you more than once, the correct solution is simple... 1. Stop forwarding spam, or 2. Do not forward *any* emails, period. If you absolutely *must* allow your users the option to blindly forward *all* incoming mail to another account, then you need to do one of two things: 1. Disable *all* spam filtering on the target address, or 2. Implement some kind of additional spam filtering on accounts that forward mail that refuses to forward any mail with a very *low* spam threshhold. If you cannot do one or the other reliably, then you will continue to have the problem. -- Best regards, Charles
