Spam forwarding help needed

I would like to set the VM server to only forward messages that have been spam filtered. Currently, it is forwarding all messages when set to forward a copy. Is there a way to achieve this?



Seems no-one know how to avoid this. How about any tips on how virtualmin forwards mail, (at what point in the process), as then I can work on it, and try to get procmail to filter it, or something…

Anyone know what is modified by the forwarding option in the mail user settings for a domain?

I would also like to know the answer to this question.
