When I have a mailbox forwarded automatically (in Virtualmin Users), the forwarding apparently happens before SpamAssassin sees the message. I'm worried about my server reputation, because I'm seeing other servers—especially Gmail—refusing delivery. Spam messages are getting stuck in the queue. Is there a way to have messages scanned first and spam dropped instead of forwarded?
I guess I'm really asking how to filter all outgoing email with SpamAssassin, because there's always a chance my users could send spam too.

Hi,
I think it wouldn't be possible to achieve that unless the mail first hits your local mailbox, and only then gets forwarded.
Okay, I have ManageSieve working, so I'll try that.
